sipcalc VS cli

sipcalc on the command line is my go to. https://github.com/sii/sipcalc

Similarly in the real world we use a calculator such as sipcalc.

Note: You can check the quality of SOCKS5 or HTTPS proxy with companies like: https://ipinfo.io or whoer.net

You need an access token from ipinfo to access their API. Go to ipinfo.io and sign up for an account. After signing up, you'll get an access token. Keep it handy as we'll need it in the next step.

3- IPinfo

Mullvad VPN location set to Frankfurt germany

Using the us east test server:

Proxy Score: 10/100 - Very likely not a Proxy

VPN Score: 0/55 - Very likely not a VPN

Using german test server:

Proxy Score: 10/100 - Very likely not a Proxy

VPN Score: 30/55 - Very likely a VPN

The thing that changed between both tests was the flow latencies vs ping latencies check. Clicking on more info it said: "flow variance too large in relation to avg flow: 0.6937484181219945"

I guess it works kinda, but not very consistent.

But e.g. https://ipinfo.io/ reveals immediately that this IP is a VPN IP address.

If it's a work computer it may be connecting to it's own VPN automatically. If you go to a site like https://ipinfo.io/ do you recognize the external IP address, region, and org?

Then just check IP of the server when ping is high for you, put IP in https://ipinfo.io/, and block range for all other servers in same datacenter.

3. Check the IP address information by ipinfo.io, and confirm the IP location information is right with okeyproxy's we pasted into ProxyHelper.
