i think you made a big typo on your netmask.. i'm gussing you mean 255.255.255.252.. if you have a 255.255.252.0 that would be well over a class C.

if you meant 255.255.255.252 then you can use 2 ip addresses

you should talk to your provider, they may have given you that subnet mask however that does not mean you get all the IP's within that subnet mask.

255.255.252..0 is the equal to a /22 which means you have like 1024 ip addresses.. but i highly doubt that..

/26 = 64
/25 = 128
/24 = 256
/23 = 512
/22 = 1024

see a pattern?

* sorry.

a 255.255.255.0 = 1 class C
255.255.254.0 = 2 class Cs

so in a class C you have 256 ips..

so you have a 255.255.252.0 so thats 4 class C's

4*256=1024
