what do /27 /26 etc mean for ips?
 

if i have this:

1.1.1.60/27

2.2.2.70/26

3.3.3.3/27

what does /27 mean?

does it mean from 1.1.1.60 - 1.1.1.254?

it tells you what the network and the client IP's are based on the number of bits in the "slash". So if it's a /24, it would be class C because the /24 bits take up X.X.X.

if you get /27 its a subnetted network class C network with 3 extra bits on the network side.

would be 32 ips

Best answer goes toooo ....... Official Babe!. Here is a star.

That tells you how many usable hosts you can have using that IP.

For your pleasure.
