What Does VPN Traffic Look Like?

VPN traffic looks like normal internet traffic. There is no special VPN traffic that can be identified as such. However, when you connect to a VPN server, ISPs see nothing but encrypted traffic, so it will look like gibberish to anyone who tries to intercept it.

The most commonly used level of encryption is 128-bit AES, which is virtually impossible to crack. So even if someone could intercept your VPN traffic, they wouldn’t be able to read it.

However, ISPs are not stupid, and they can usually tell when you’re using a VPN. They may throttle your connection or even block VPN traffic altogether. That’s why it’s important to choose a VPN provider that doesn’t keep logs of your activity, so your ISP can’t see what you’re up to.

To overcome this, a VPN must have DNS Leak Protection and a Kill Switch. DNS Leak Protection ensures that your traffic is always routed through the VPN’s servers, so your ISP can’t see what websites you’re visiting. A Kill Switch kills your internet connection if the VPN connection drops, so your traffic is never exposed.

How Do I Check My VPN Traffic?

To check your VPN traffic, you can use a packet sniffer such as Wireshark. Just make sure that you’re connected to the VPN first. Then start Wireshark and look for any DNS or IP requests that are being made outside of the VPN’s servers. If you see any, then your traffic is leaking and you need to find a better VPN provider.

What Does VPN Traffic Look Like To Router?

If you have a router that supports VPNs, then your VPN traffic will look like any other traffic passing through the router.

Can VPN Host See Traffic?

If you’re using a reputable VPN provider, then the answer is no. The VPN provider will be able to see your traffic, but they won’t be able to read it because it will be encrypted.
