How many possible networks can i get out of a /24 using vlsm ? would it be 2 x /25 + 2 x /26 and so on, can anyone tell me by doing a list

thanks a million

Example:

192.168.11.0/24

-> 192.168.11. 0|0000000 >> 192.168.11.0/25

-> 192.168.11. 1|0000000 >> 192.168.11.128/25

192.168.11.128/25

-> 192.168.11. 10|000000 >> 192.168.11.128/26

-> 192.168.11. 11|000000 >> 192.168.11.192/26

192.168.11.192/26

-> 192.168.11. 110|00000 >> 192.168.11.192/27

-> 192.168.11. 111|00000 >> 192.168.11.224/27

192.168.11.224/27

-> 192.168.11. 1110|0000 >> 192.168.11.224/28

-> 192.168.11. 1111|0000 >> 192.168.11.240/28

192.168.11.240/28

-> 192.168.11. 11110|000 >> 192.168.11.240/29

-> 192.168.11. 11111|000 >> 192.168.11.248/29

192.168.11.248/29

-> 192.168.11. 111110|00 >> 192.168.11.248/30

-> 192.168.11. 111111|00 >> 192.168.11.252/30

192.168.11.252/30

-> 192.168.11. 1111110|0 >> 192.168.11.252/31

-> 192.168.11. 1111111|0 >> 192.168.11.254/31

that's just an example ... Improuve your subnetting ;)

wow, thanks for that, is there a table you can work this out on ? so can you use all them networks at once on the same site, and they are all represented by the /24 ?
