Say I have a network object group object in my firewall, and I wish to add in not just an IP but a range of IP's. 18.104.22.168 to like 22.214.171.124? I hope I am doing this wrong by entering in 10 ips vs just a range of some sort.
How do you go from 0 to 8 to 10? And then even choose the net mask from 248 to 254? I'm trying to figure a pattern to so I can replicate this into more ranges. I can read relative links. Like say I'd block a whole range. 10.1.1.*
248 indicates the first 5 bits of the 3rd octet need to match but it doesn't care about the last 3 bits (address range of 0-7). A quick search on Netpro should find lot of useful links on subnetting. Here's one I found on google that may find helpful.
Too bad there wasn't a Cisco website tool like http://www.cisco.com/cgi-bin/Support/IpSubnet/home.pl that we could enter a desired range and have it calculate it. That would be perfect while reading your article as I read theory but sometimes (like this time) need to exercise correct and incorrect'ed'ness to help reinforce understanding.
Got more articles? I tried searching netpro but got lots of unrelated articles.
