Hi, a noob here. Bought myself a RB411 and setting up DHCP. What is the suffix 24 (as in 10.0.0.2/24) for? Any help appreciated. :roll:

It's the "subnet mask". /24 is equivalent to 255.255.255.0. Means 24 bits are 1s starting from left to right. The remaining 8 bits are left as 0s.

Another one, when we say /15 that means 15 bits are 1s and the rest are 0s. Equivalent to 255.254.0.0.
