Question : Question on external IP

At work, I know my external IP adddress by looking at www.whatismyip.com... is there a way to find out the range of IP's owned by my company?  I need to provide to a web host for an access list and there is noone here from our IT department to ask.... Thanks...

Answer : Question on external IP

The block owned is:
My  company name . xx.xx.135.192 - xx.xx.135.255

This is assuming the first two octets are the same (e.g. 192.168.135.x) you have /26 block which you can write in CIDR as:
x.x.135.192/26
