Hey Guys,
Ive just started targeting via ip ranges but alot of networks will provide the subnet like - 181.68.0.0-181.68.159.255 and ad networks need this broken down to - 181.68.0.0/17 - 181.68.128.0/19.
I can do the math but its a time killer, are their any tools that can automate this process?
Let me know thanks again.
Guys I found one - quicker than I thought it be! - http://www.ipaddressguide.com/cidr#range - for anyone thats interested
Even better 
Hit me up on pm if your new on the scene maybe we work on some stuff.
Been in the industry for 5 years but just moved into the aff space, no worries if not, thanks either way!
If targeting a specific carrier, I like to use this website http://ipinfo.io/countries/ca
Just replace last two letters in that URL with the country code of your choice. Then pull all the netblock ips from the carrier you wish to target.
This one is also good, calculations in bulk: https://www.cidrcalculator.com/ipv4/...ip-range-bulk/ (they got more ways of calculations, just hover over the menu)
