You can only split networks in half, so you can have: 128 addresses (126 usable) 64 (62 usable) 32 (30 usable) 16 (14 usable) 8 (6 usable) 8 (6 usable) <---- put your 4 here But now you're looking at 6 subnets, which isn't what you want. Don't know of a way round this , and you're looking at connecting all those separate subnets with a lot of networking kit. So basically, find another solution that doesn't require 4 Ips on their own subnet. How about 128 on their own subnet? -- Bipolar, adj.: Refers to someone who has homes in Nome, Alaska, and Buffalo, New York Rasputin :: Jack of All Trades - Master of Nuns :: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
