Got a question for you computer/network guys....part of my new job is searching through IP ranges to see if certain one's are blocked or not....and I'm looking for a solution. Don't care if web based or via another program or whatever. Basically say if I find an IP of 255.255.3.56 and I want to see if it falls within this range 255.255.0.0 0.0.147.255 is there a simplier (easier and faster) method of searching vice doing the manual calculation of that?
Thanks for any help.
Not sure if this is any use to you, as I'm tired as fuck and just came back into work, but might this be of some help?
Email Blacklist Check - See if your server is blacklisted
EDIT: I'm guessing not. I'm retarded.
