I recently found the below answer to a question posted as to whether
you
could delete and re-create a subnet address range and the answer
partially
is the answer to my question

Answer: No, it is not possible. It is not "safe" to delete and
recreate
(but it can be done with a little risk, make sure that Ping Ahead
Enabled
is checked, this will help, but you may still get duplicate address
problems), you can INCREASE a Subnet Address Range simply by adding a
NEW
subnet address range. You could TRY to decrease a range by exporting,

editting, importing [at your own risk of course], but there will be a
lag
before workstations comply with the new range.

I created a new subnet address range to INCREASE my subnet address
range,
bound it, and addresses were being handed out in the new range by the
DHCP
server. Problem is that our Groupwise e-mail and proxy are on that
same
server and the internal IP address for that server is in a different
IP
subnet range and therefore those workstations that got the new
addresses
can't get out to the Internet or to their Groupwise e-mail. (original

range 10.10.1.x with the proxy/e-mail server having 10.10.1.9 and NEW

subnet address range having 10.10.3.x addresses)

Can someone tell me how to resolve that issue? I'll be forever
grateful
if I can solve this dhcp address problem I'm having with running out
of IP
addresses.

Thank you very much!
