So the answer is: 1) Use DHCP for all of your colo'd hosts. 2) Use two nameservers that are not colocated, or provided by a provider you feel comfortable with. Then you just update your DNS/DHCP records and renumbering isn't a pain.

If you (BGP) peer with the ISP(s) at the Colo facility, then you can advertise your Ip space and it will work at any facility. The bad news is that if you advertised Provider A's Ip space, and then go to a colo not served by Provider A, they will (rightly) want their Ip's back. If your Ip requirements were large enough to justify "Provider independent" space, then it would be portable everywhere. Good Luck, Ejay -----Original Message----- From: Mark J.

The obvious advantages being greater capacities for bandwidth, power, cooling, and oh yes, proper methods of putting out a fire (instead of drowning the servers in water if they so much as overheat). The concern I have is this: if we decide a few months down the road that we don't like this particular colocation facility and wish to move to another one across the street, I'd have to renumber all of my hosts. Is it possible to go to any colocation facility with a block of IP addresses in hand and use them? I'm talking about a /24 here, so I cannot request the addresses directly from ARIN, rather I need to get them from some other source. I attempted to get them from our current bandwidth provider, but they seem to be a little taken aback by my request for a block of addresses that will not be routed by them -- in fact, while writing this they called to tell me they will not provide IP space unless they route to it. Is there a better way to get a /24 that can "go anywhere"? Or should I just justify a /24 at the colocation facility and go through the same process should we decide to change? Is there a way to buy a routable /24? Thanks in advance for any advice, on or off list. I will summarize unless the answer is "you're crazy, such things aren't possible" in which case I'll be off drowning my sorrows at a nearby watering hole. Mark J. Scheller ([email protected])
