Several years ago, there was a group convened to discuss the matter
under the ribric 'rfc-roam', with the goal to develop an RFC for "common
shared IP for easy roaming". Last message I show was from Mon, 1 Jun
1998 11:37:12 +0100 (BST); i presume the list died off, as I don't
recall unsibscribing.
It is interesting to note that the problems of applying this methodology
in a port wholesaling environment did not come up; I think the membership
was composed mostly of folks who would be considered the 'wholsalee'
rather than the 'wholesaler'. But the list did spring from a
conversation like this on NANOG ... the archive used to be at
ftp://ftp.uk.psi.net/psi/rfc-roamip, and that's gone;
rfc-roamip@uk.psi.com was the address...
Cheers,
Joe
