Re: Run out of IP addresses

That's true. Heck you could probably go to maybe 400+ machines on a segment
if it is a situation where they aren't all turned on at the same time,
especially if it is fully Switched and runs over gigabit.

But I don't believe in creating a Topology that gives you the easy abiltiy
to do something you should not do, that is, create a situation that
encourages a bad practice. It's like the phrase "give'em enough rope and
they'll hang themselves". Also once you create a Topology like that and
machines are placed on those addresses that "spill over" into the addresses
beyond what the /24 mask would have given,...it can become complicated to
"fix" that and redesign the Topology back to what it should be. It is
always easier to expand a segment than it is to shrink it back to what it
should be after it is grown out of proportion.

Agreed, but... I don't think moving from 200 hosts to 201 hosts would make
any difference to his current performance (which he seems to be satisfied
with). Of course, he didn't really say how far he would expand. Just that
he ran out of IPs.

No.
Ethernet degrades after 250-300 host
Masks should never go below /24 bits (255.255.255.0) unless it is a
backbone where multiple subnets are "superneted" over the high-speed
backbone.

The subject says it all.

I have five Windows 2003 servers, each running various business apps
including a Manufacturing Systems, Exchange Server 2003, a separate SQL
Server 2005 box.

I have roughly 200 hosts, with a variety of print servers, wireless
access
points etc. I have one ADSL connection, which is the default gateway on
all
machines.

I am running Active Directory on all servers with the DHCP scope
ranging
192.168.50.1 thru 192.168.50.254 with a subnet of 255.255.255.0

Print servers, wireless access points and the router all have
reservations
in the DHCP scope.

The problem.

I need more IP addresses.

I am looking for a step by step guide to adding another subnet to the
network so that all hosts on the new subnet can speak to the existing
servers and share the ADSL connection.

Thanks in advance

Maurice





Just change your mask to 255.255.0.0 and widen you scope from
192.168.50.1 thru 192.168.50.254 to 192.168.50.1 thru 192.168.51.254.
