DHCP issue, I'm stumped

DHCP issue, I'm stumped

DHCP issue, I'm stumped

We are setting up a DHCP server and are running into issues.   We want to have more ip address so we have setup two scopes and entered them into a superscope.  The scopes are:  

Server ip is

Ip addresses ge assigned no problem.  The issue happens when the ones isnt he 7 range get used up and the clients begin getting the 8's.  The 8's cannot ping any systems with the 7 addresses except for the gateway server.  We put a second ip address on the DHCP servers card with an 8 address but that didn't help either.  

Any help would be appreciated.  Thanks


RE: DHCP issue, I'm stumped


What subnet mask are you using for these scopes?


RE: DHCP issue, I'm stumped

Change the mask from on the router to that of the DHCP scopes superscope mask.  Your router address only knows about the network. is a separate network and requires a router to pass traffic to the 7 network.  I would think that would do thie trick.  To be sure, run it through a subnet calculator.  

Try this link for more info.


RE: DHCP issue, I'm stumped

Yes, WHOHEARD, the is the right mask to go with - gives you 512 hosts/subnet (unless you need more addresses), but you cannot supernet the subnets you use now.
You can do - 7.254 or - 9.254.

Good luck.

RE: DHCP issue, I'm stumped

Yes, how true.  That would be a problem.  Thanks for catching that.
