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.

If you *own* the block, you can do anything you want with it.

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.

"Ownership" is not the word to be using. The 205.238.192/18 is ALLOCATED to Epix. Meaning: the are authorized to use the addresses or to assign them to someone else to use. The /24 is probably ASSIGNED to you. Meaning: you can be an end user of the addresses. The /18 is not registered with ARIN as non-portable, so the portability call is exclusively up to the administrator of that block.
