uhhh no. Ben had it right. With a subnet mask of /22 that covers 10.5.0.0-10.5.3.255 and then the /24 covers 10.5.4.0-10.5.4.255. There is no point to writing them all out like that, especially with the /32 why add in a NET for a single ip? That is an odd range of ip's though, it doesn't fit in well with CIDR style notation. is this 1 network with a netmask of 255.255.251.0??? strange.... 10.5.0.0/21.5-ish ;-) Out of curiosity are these networks split across multiple interfaces? --Bryan On Tue, 2003-07-08 at 13:03, Brian wrote:

You would also look at 10.5.0.0 and 10.5.4.255 which don't fit in the range specified. For the most part, that will work, but if you want to be exact, you need: var HOME_NET [10.5.0.1/32,10.5.0.2/31,10.5.0.4/30,10.5.0.8/29,10.5.0.16/28,10.5.0.32/27,10.5.0.64/26,10.5.0.128/25,10.5.1.0/24,10.5.2.0/23,10.5.4.0/25,10.5.4.128/26,10.5.4.192/27,10.5.4.224/28,10.5.4.240/29,10.5.4.248/30,10.5.4.252/31,10.5.4.254/32] aggregate is your friend. (echo 10.5.0.1 - 10.5.4.254 | aggregate -i range) -brian ------------------------------------------------------- This SF.Net email sponsored by: Parasoft Error proof Web apps, automate testing & more.
