Hello,

i had list of ~80 tracker announce URLs:

https://open.kickasstracker.com:443/announce
https://zer0day.000webhostapp.com:443/announce

udp://tracker.zer0day.to:1337/announce
udp://z.crazyhd.com:2710/announce
udp://zephir.monocul.us:6969/announce
And i wanted to use IPs instead of host names / domain names.
Behind each domain/hostname is a IP, so it will also work if i replace example: tracker.zer0day.to:1337 by 1.2.3.4:1337

NOTE: that IP is less permanent and less reliable way, trackers are changing IPs more often than host names!

I created two lists out of mine, one for udp urls and other for http urls.
Then http list i converted to IPs using: http://domaintoipconverter.com/index.php

It is hard to do, maybe there is easier way to do it.
