Suppose I'm part of the network 192.168.0.0/24. In a general, what does the /24 mean? I see this all around, but I never know what it means. If anyone can shed some light, It'll be greatly appreciated. __________________ __________________ Awesomeindustries.net

You have 24 bits reservered for Subnet Mask and you may borrow from the 8 bits in the host field too create more subnets on a LAN.

In your question the following apply's, subnet /24 = 255.255.255.0 11111111.11111111.1111111.00000000 Wild Card = 0.0.0.255 00000000.00000000.0000000.11111111 With your wild card /24 here is how it works out: Network address = 192.168.0.0 First usable address = 192.168.0.1 Last usable address = 192.168.0.254 Broadcast address = 192.168.0.255 You will have 254 availabls host addresses. Subnetting can be tricky so this is just really simplified without going through the bits here... __________________ __________________
