ipchains

Ok, Im working here with ip chains:

I got the following setup:

/sbin/ipchains -N dkbhst
/sbin/ipchains -I input -j dkbhst
/sbin/ipchains -I output -j dkbhst
/sbin/ipchains -A dkbhst -s IP/255.255.255.255 -p all
/sbin/ipchains -A dkbhst -d IP/255.255.255.255 -p all

This basicly counts all traffic to the stated IP

Then I get the output:

3966 502K - all ------ 0xFF 0x00 any 128.xxx.xxx.0/27 anywhere n/a

5068 297K - all ------ 0xFF 0x00 any anywhere 128.xxx.xxx.0/27 n/a

Thats two, one outgoing, one incomming:
I got that with this command
/sbin/ipchains -L dkbhst -v

This is what I dont get, and I am new to ipchains, and well I typed in the ip address at the first few commands as 128.xxx.xxx.22 and in the output it lists as 128.xxx.xxx.0/27

Is that just their way of writting it, or is it tracking for all ips from 0 to 27?

Thanks

EDIT
Never mind, it was the netmask
