My ISP is changing upstreams for a variety of reasons around May 18th. 1. I have a /24 SWIPed to me, 205.238.207.0. The ARIN listing doesn't say it's non-portable, so can I take it with me? And if I do, how likely is it that the new ISP's announcement will get installed in backbone routers rather than filtered for being too long? It's right in the middle of the old upstream's block 205.238.192/18. 2. Assuming I have to renumber, I have a whole bunch of virtual domains all DNS served from one server in the renumbered space called ivan.iecc.com. (There's other servers elsewhere that won't get renumbered.) If I tell the Internic that ivan's host number has changed, will that update all the domains served from it? TIA.

That is unfortunate.

If you *own* the block, you can do anything you want with it. I don't think there is an issue with with routing, you just have to do it. Then again, I may be wrong.
2. Assuming I have to renumber, I have a whole bunch of virtual domains all DNS served from one server in the renumbered space called ivan.iecc.com.

Sure, a host modify (http://rs.internic.net/cgi-bin/itts/host) will set you up. If you can, I'd try to overlap service so when things fubar, you can always fallback to pieces-parts 'till you can figure things out :) -ravi

Well, there's the question -- I have no idea who owns it. Look it up in ARIN, it says it's mine, but with contact info from epix, the old upstream. Again, though, even if I own it, if the announcements don't make it into the backbone it's not very useful, and I gather that some backbones now filter at /19 except for the swamp.

My ISP (the local independent telco who is quite sharp) is doing what they can but epix is less than helpful.

I have a similar issue with a /21 which should belong to me. It's in the middle of UUnet's block. They have claimed they own it in private mail, but neither of us have actually updated the contact record, which indicates my predecessor owns it. For now it's fine, since I like uunet, and probably won't change that. The real problem with portability seems to be getting the route advertised. A /21 has a chance (I think), but a /24 probably is going to be tough. My guess is that you won't be able to get anyone to route it, and even if you do, it might not be accepted globally.

Yes. Thats the beauty of Host records. Your domains have a host handle. When you update the IP associated with that handle, all the domains that use that handle are also updated. To make this go smoothly, you will need a secondary nameserver in your whois records that won't change, so you will still have service during the overlap. --Dean ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Plain Aviation, Inc dean@av8.com LAN/WAN/UNIX/NT/TCPIP/DCE http://www.av8.com We Make IT Fly!

I can't imagine that a /24 would be advertised, if at all, by anyone besides the direct upstream of the site using it. -- Steven J.

If you change the InterNIC Host Record for a name server, it should be reflected in the whois info for domains that use that name server (works that way for me, anyhow). You may need to notify ARIN separately. -- Steven J.
