How Does A VPN Change My Ip Address

How VPNs use tunneling and encryption

Your public IP is the address of your device on the internet, and is the digital equivalent of the postal address of your house .

When you use a VPN, as weve already seen, your device connects to one of the VPNs computers elsewhere on the internet. In effect, your device and that server become part of a private network of sorts a virtual network, hence the name Virtual Private Network. To all intents and purposes, the VPN server is then seen as the origin of the data coming from this private network.

So your real IP, the digital address of your device, is effectively hidden, and the source of the data appears to be the VPN server, which has a different IP address. In effect, that different IP now appears to be your IP address.

To summarize, then, technically this isnt a case of changing your IP, so much as hiding your real IP away behind the IP address of the VPN server.

Are VPNs Free And Are Free VPNs Safe

Free VPNs exist, but theyre usually far less secure than leading premium VPN services. A free VPN service may replace subscription fees by showing you ads or by collecting and selling your personal data. Other problems with free VPNs include:

  • Weak protocols: Most free services provide only PPTP , an obsolete method built in the 1990s. Several PPTP vulnerabilities have been discovered over the years, and the encryption can be broken easily using tools that are widely available online.

  • Slow speeds: When everyone crowds onto a free VPN, its servers can quickly become overwhelmed, delaying connections and slowing things down.

  • Bandwidth limits: Free VPN services often have restrictions on the amount of data you can use per day, while most premium VPNs offer unlimited data.

  • Fewer server locations: A free service rarely supports as many locations as a leading premium VPN service.

  • Advertising: Free VPNs may insert ads into websites that might not usually have them, which isnt just annoying it can also be a security risk.

You can experience the benefits of a leading premium VPN service with a 7-day free trial for AVG Secure VPN. Hide your IP address, protect your personal data, access all the content you want, and secure your internet connection.

How A VPN Protects Your Ip Address And Privacy

VPN Encryption Explained

Once you log on to a VPN that is, once you enter the encryption tunnel the VPN hides your data from anyone who might want to see it. In the simplest terms, what you do online when you are connected to a VPN is completely private. One of the advantages of a VPN is that the privacy extends to your IP address, the identifying information of your device that lets others know your location. When you log in to a VPN, you can connect to a server in a number of locations around the world. In addition, the VPN issues you an IP address that conceals your actual IP address. The end result? You are absolutely anonymous.

Selecting A Secure VPN Provider

It is also important that you choose a VPN provider that you can trust. While your ISP cannot see your internet traffic, your VPN provider can. If your VPN provider is compromised, so are you. For this reason, it is crucial that you choose a trusted VPN provider to ensure both the concealment of your internet activities and ensure the highest level of security.

They Can Exploit Human Error

As with just about anything in the world of online security, the weakest link is human. Suppose a VPN provider creates a vulnerable network that is easy to exploit or one of its employees becomes compromised.

In that case, hackers can access the information needed to circumvent encryption to gain access to your data.

Unless you are doing high-profile or high-value work, it is unlikely that you will be directly targeted in an attack.

However, if a VPN service becomes a target and you use it, you may become a victim of such an attack, even as collateral.

VPN Providers For Consumers

Greece No

This is just a small selection of the available VPN providers. There are some really good VPNs on the market, a lot of mediocre VPNs and many more bad, misleading or even dangerous VPNs.

At VPNOverview.com we analyze developments in the VPN industry, read independent audit reports and monitor lawsuits involving VPN providers.

Unfortunately, quite a few VPN providers have fallen off their pedestal over the years, for example because lawsuits showed that they secretly kept logs of users . In addition, there are also some VPNs that are linked to questionable governments.

Choosing a reliable VPN is therefore a must after all, you redirect all your internet traffic via this party. That is why you must be able to rely 100% on the good intentions and integrity of the VPN provider you choose.

Layer 2 Tunneling Protocol

This protocol combines PPTP with the Layer 2 Forwarding tunneling protocol. It strengthens the data tunnel provided by PPTP but does not provide users with encryption or privacy capabilities. As a result, the protocol is typically bundled with a security protocol such as Internet Protocol security .

Rule #2 You Probably Dont Need 256

AES-128 is still considered secure, and is regularly used by businesses and governments for secure communications. Its pretty unlikely that anybody is targeting the decryption of your data specifically, or that the NSA would be terribly interested in what youre actually doing online.

Since AES-128 is substantially faster than AES-256, most users would be better off choosing 128-bit encryption .

If, however, you are generally concerned about keeping your data as safe as possible then definitely use 256-bit encryption.

What About Using A Smart Dns Or Tor Instead Of A VPN Service

A Smart DNS is a simple service for people who want to access geoblocked content. Smart DNS services wont encrypt your internet connection, which means they wont keep you safe on public Wi-Fi like a VPN can. This is just one of the many differences between a Smart DNS and a VPN.

Tor is free and open-source software that anonymizes you over the internet by encrypting and bouncing your connection through multiple servers, or nodes. While Tor is powerful, it isnt airtight.

Since your traffic is unencrypted when it leaves the Tor network, hackers and governments can monitor these exit nodes and execute man-in-the-middle attacks. Some people choose to connect first to a VPN and then enter the Tor network to hide their home IP address.

When you compare Tor to a VPN, youll notice that Tor is very slow. And since its network is maintained by volunteers, using it to download or share large files is discouraged. A VPN service will give you much faster speeds, without limits on what you can do while connected.

What Is VPN Encryption

VPNs: How They Work and Why You Really Need One

At its core, encryption is a way of converting data from a readable format to an encoded, unreadable format with the help of an algorithm. Said encoded format can only be decoded with the right decryption key.

Going off of that statement, VPN encryption can be defined as a means of encrypting plaintext data to make sure it shows up as indecipherable gibberish to anyone who tries to monitor it .

Which Is The Best VPN Encryption

Choosing the best VPN encryption can become a daunting task for new netizens. You will have to consider different factors before selecting an appropriate type of encryption. Luckily, you have arrived at the right place. We have outlined some of the best VPN encryption types that include:

  • AES-256
  • AES-128

AES has become a benchmark when it comes to exploring electronic data encryption standards. It consists of three main block ciphers like AES-128, AES-192, and AES-256. Therefore, you can assume AES-256 as the safest encryption level as it provides both anonymity and security to users.

AES-128 on the other hand is more convenient option as it does not need much resources. Still, if you do not want to compromise on your privacy, AES-256 is the right choice.

Secure Your Data Over Public Wi

The convenience of free public Wi-Fi often comes with a loss of security. Since anyone can hop onto an unsecured Wi-Fi network, theres no way to know exactly whos connected at any given time, or what theyre doing. Its easy for a hacker to sit on a public Wi-Fi network and intercept all the traffic flowing across it.

If you log into your bank account, check your email, or hang out on social media, a hacker can snap up your login credentials. Any messages you send or personal data you transmit can be intercepted and used for blackmail or identity theft. The risks of public Wi-Fi are almost endless.

Because a VPN connection encrypts your communication with its server, anyone trying to eavesdrop on the public network will see only gibberish. Thats a big part of what VPN protection is: ensuring that no one can access your data.

Should I Use A VPN At Home

VPNs are especially useful when you are browsing the web through public Wi-Fi, whether you are at a coffee shop, hotel lobby, or public library. But a VPN can also protect your privacy when youre at home, keeping your browsing safe from prying eyes. You can also use a VPN to access streaming content from your home that might be otherwise locked in your area.

How Does A VPN Work For Torrenting

How a VPN works

This is a thornier issue, because some VPNs dont work for torrenting at all. Some VPNs dont support torrent users, and others may only support such P2P file-sharing on certain VPN servers .

This could be for bandwidth reasons , or legal reasons .

So, the initial consideration if you want a VPN for torrenting is to pick a provider which supports them and weve rounded up the best torrenting VPNs here for your convenience.

As to how the process actually works when torrenting, its the same as a VPN normally functions, the key parts here being that your IP address will be hidden, so actions cant be traced back to you, and your traffic is encrypted, meaning no one can see what youre up to online or downloading.

That all said, using a VPN doesn’t make downloading pirated films, music and files any more legal. And it’s not something we condone at TechRadar at all.

Are There Any Downsides To Using A VPN

The added security and privacy youll get with a VPN makes them an essential tool for internet safety. VPN disadvantages are few, but one side effect might be a slight reduction in your internet speed. This is because a VPN encrypts your internet connection and redirects it through a VPN server.

The VPN marketplace is highly competitive, and many leading VPN providers are committed to keeping their services as fast as possible.

Are VPN And Encryption The Same Thing

A VPN tunnel is a method for connecting your device to the destination in the web using an encrypted connection. By using a VPN tunnel, you are not only encrypt your data, but you are also protected from prying eyes and your IP address and location are hidden.

How Does A VPN Work To Keep Me Safer Online

As weve seen, first and foremost a VPN provides security when youre online by encrypting the data you send, keeping it safe from prying eyes like your ISP. While your ISP can see that youre connected to a VPN , all the data flowing through its systems will be encrypted, so the ISP wont be able to make any sense of it.

Therefore the ISP wont be able to leverage your data to its own purposes .

Furthermore, when you go online in riskier scenarios like using public Wi-Fi at an airport or café, for example where your data is potentially more likely to be compromised by a malicious party, again, because the data is encrypted by the VPN, youre much safer because that party wont gain anything from its snooping.

As well as greater security, a VPN gives you anonymity, changing your IP address to be different from what it actually is in other words, replacing the address of your computer with the address of the VPN server, as weve already discussed.

This means your online activities cant be traced back to your device, potentially keeping you safe from invasions of your privacy, or maybe even more direct threats like targeted DDoS attacks that disrupt your internet connection. Volleys of DDoS aimed at individuals may be very rare, but cheating gamers arent beyond using something like this to sabotage a rival.

How VPNs Can Unblock Streaming Sites

Do VPNs Actually Protect Your Privacy?

As weve already mentioned, VPNs are capable of much more than simply keeping users safe on the internet. With many of the top streaming VPN services, you can unblock streaming platforms globally.

But how? Its actually pretty simple. Most premium VPN providers operate thousands of servers globally, and when you connect to these, you can appear to be elsewhere in the world and subsequently avoid geo restrictions. For example, if you want to access the US Netflix catalog in the UK, youll need to find a US VPN server and connect to it. Then, Netflix will see you’re connecting from a US IP address and think youre physically located in the US, and provide access to its American streaming catalog.

Encryption On Whatsapp And Social Media

Youd probably prefer to keep your messages on WhatsApp private. Nobody should have access to that information except you and the person youre messaging. To ensure this, WhatsApp has been using end-to-end encryption since 2016. You may recognize the message below from your own WhatsApp conversations:

In 2014, WhatsApp was taken over by Facebook. Since , many users were concerned about their private messages on WhatsApp after this buy. End-to-end encryption, however, ensures that no one, including Facebook, can view your WhatsApp messages. The same goes for your WhatsApp phone and video calls. This encryption is enabled by default, so you dont have to adjust any special settings in order to enjoy this protection.

End-to-end encryption isnt unique to WhatsApp. Other platforms and social media also use it to protect user conversations. Think of Facebook Messenger, Snapchat, Telegram, Signal and Wire. Some popular anonymous email providers such as ProtonMail also use this form of encryption.

Other VPN Encryption Methods

All of the premium VPNs use OpenVPN for their security strategy. However, there are other VPN protocols around and many VPNs offer these in addition to OpenVPN. Not all of these systems are presented in an app. In most cases, these additional systems are available to be set up manually within your devices operating systems settings.

The major alternatives to OpenVPN are:

  • PPTP
  • IKEv2/IPSec
  • SSTP

None of these alternatives to OpenVPN are recommended if you need top-level security and strong privacy. However, there are circumstances where these systems might match your VPN needs.
