DHCP Pool

Dale812Dale812 Posts: 15Member ■□□□□□□□□□
Setting up DHCP pools for the 3 networks below:

192.168.0.0-7 /29
192.168.0.8-15 /29
192.168.0.16-47 /27

I set the pools up for the first two /29 networks and are assigned to the correct range of IP's but when I setup the pool for the /27 network it sets the pool range at 192.168.0.1 - 192.168.0.30. Any idea's? Cheers!

Router-1(dhcp-config)#do sh ip dhcp pool

    You are crossing bit boundaries.

    /27

    0-31, 32-63, etc...

    do the address and mask in a binary "AND" and you will see where the boundaries are.

    bit boundaries.... in other words, block sizes.. You can't do sizes of 8 than jump to a 32.. best to do the large block first than the 8s..If you have to stick with the 32, than start it at the .32 IP address after the 8 block size
