Networking question [I Fix Computers]

Hey guys,

This question is for network admins who do this everyday I am wondering how our wireless routers hand out ip addresses when using the default subnet mask with a cidr notation of /24 which is a class C address scheme how would you figure out the usable ip addreesses computers would get say 192.168.0.xxx what addresses can it use and where does it stop or where is the Cap?and what happens why would this private address on a computer change?

I look forward to hearing from you guys Thanks Gabe.

I'm not quite sure what you're aiming for with this, so I might be a tad pedantic. addresses are handed out by a service running on the network called dhcpd (dynamichost configuration protocol daemon), which can be configured to send any of the available network addresses and keep track of them. as far as which addresses can be used on a network, you know the octets already, 0-255 [256 total]. in the case of a class c, that's one 8 bit octet to use for hosts and every network loses 2ips, one for the network, one to broadcast. so a 192.168.0.0/24 has 0.0 for network, 0.255 for broadcast. if you changed that to 192.168.10.0/23, 0.0 is still network and 1.255 becomes broadcast.

conversely, a 192.168.10.0/25 loses half the network, broadcast becomes 0.127, and the max range is from 1-126 on the last octet.

hope this is of some use.
