Hosts Netmask
/30 4 255.255.255.252
/29 8 255.255.255.248
/28 16 255.255.255.240
/27 32 255.255.255.224
/26 64 255.255.255.192
/25 128 255.255.255.128
/24 256 255.255.255.0
/23 512 255.255.254.0
/22 1024 255.255.252.0
/21 2048 255.255.248.0
/20 4096 255.255.240.0
/19 8192 255.255.224.0
/18 16384 255.255.192.0
/17 32768 255.255.128.0
/16 65536 255.255.0.0

I assume that x.x.x.5-x.x.x10 are usable ip addresses, with that we can conclude that x.x.x.4 is Network ID and x.x.x.11 is a broadcast address

so the mask will be 255.255.255.248 or /29

iwill try to explain what i need

i using pppoe and i need make apool for 2 ips
i creat it x.x.x.2-x.x.x.3 now this pool is have 2 ips only
now i want to using scr-addrees for 2 ips only (x.x.x.2-x.x.x3) some rules didn`t agree ips they need x.x.x.x/?
so ineed to learn about subnet if any one have post or article about this ?

Check if the rules will take a range - 1.2.3.4-1.2.3.5.

A 2 host range has ending /31.
