RE: IPv4 flag day

[Vasilenko Eduard via NANOG <nanog () lists nanog org>]

Ole Trøan did try to resolve multihoming in "Home networking" 14 years ago.
Brian E. Carpenter did try to resolve multihoming in "Site Multihoming by IPv6 Intermediation" 20 years ago.
Both failed for different reasons. Both were doing it outside of 6man WG.
