Server moves

dl763 · 7 Jan 2010 at 14:03

Hi all,

My boss is moving the servers to a different building with a different network address (current 172.16.1.x- new 192.168.1.x with no servers). Are there any special things I need to look for when moving?

Thanks in advance.

netmask and default gateway for the new network need to be correctly configured

Whats the servers function as you'll need to be careful with the DNS as well.

Thanks for the replies. One server is a 2003 SBS and the other is a standalone W2k running our billing platform running as a workstation.

If it's SBS just rerun the Internet Connection Wizard and input the new IP Details.

192.168.x.x network addresses are non routable. So they will not be able to talk to another device. They are in a private address range, that a router will not touch. unless you intend to NAT them at the perimieter of your new location.

They're moving because the company has down sized (i.e. got rid of all the staff) and the boss is putting them in his flat so that he can access all the old files.

Why cant he just keep the existing network configuration then!?

So are 172.16.x.x ........

Why does he need to change the network configuration? What talks to these servers? Is it a different network (i.e not routed to the old network?)

It'd be a lot safer to change the IP address of your bosses network at home imo.

For some reason I had 176 in my head not 172. Doh !!

Just change the 192 network to 172 and be done with it. Don't mess about with SBS and DNS just to keep a no server 192 range.

That's a deeply misleading way to phrase it, there is no technical limitation on routing RFC1918 address space, it's merely not done as a matter of policy because it exists in multiple places.

In a private network you can route between those ranges just fine though, saying they're not routable just isn't accurate, ISPs don't advertise or receive them from the global internet routing table because they're RFC1918 addresses but it's simple a policy matter.

This is probably a 30 second job. Remember to disable DHCP on the bossman's router and let SBS run its own.
