192.168.1.2/24 <---- what does 24 mean

[beefjerky911]

i see this 192.168.1.2/24 alot, i was wondering what the 24 meant, and what other numbers they had and what they meant.

24 bit mask = 255.255.255.0
32 bit = 255.255.255.255

Yep it is the number of bits identifying the network, i.e. 10.0.0.0 /8 is 255.0.0.0 or /10 is 255.192.0.0 so the first 8 bts in the first octet are turned on and the next 2 in the 2nd octet as well, the 128+64, that make any sense?

That is referred to as CIDR notation, just an alternative to the standard x.x.x.x notation for subnet masks.h You might be interested in reading more about it at the Clasless Inter-Domain Routing Overview from PacBell.
