[07:26:45] <gorryf> Multiple "endpoint" IP via some NATs comment...
[07:27:21] <gorryf> Perhaps we need a new I-D to highlight this point ...
[07:28:07] <gorryf> The current text in RFC5382 is clear (BCP). There are 3 mappings defined.
[07:28:38] <gorryf> IPv6 :-)
[07:29:35] <gorryf> Bob: This could be due to handocver
[07:29:56] <gorryf> Andrew: Wireless isn't always stable.
[07:30:45] <gorryf> Handover at L2, so it does nor change IP
