This script will convert ip or domain to country from "Server Address" column on V2rayA's web interface
This script will convert ip or domain to country from Server Address column on V2rayA's web interface (http://127.0.0.1:2017/ or http://localhost:2017/), change @match in code if you changed Address of Service of V2rayA.
The convert service is api.techniknews.net/ipgeo, read below if you wanna know more.
Search and install Violentmonkey in your browser store, then install this script.
If you are using Tampermonkey, check Always allow domain in A userscript wants to access a cross-origin resource page.
There maybe none flag shown normally and you may see Error: Promised response from onMessage listener went out of scope in F12-Console, it's a bug, you may try Tampermonkey beta.
If you are using Greasemonkey, may support in future, sorry.
I found this convert service in Github project
public-apis, try search IPGEO in that page. No Auth(api key) required and Unlimited free. Can't find much information about provider TechnikNews, you can contact them by Twitter @TechnikNewsNET .
If you can't trust this service provider, you can always change url under GM_xmlhttpRequest in code, response data structure may need change too.
