There is not much of a solution, today, for either IPv4 _or_ IPv6.
However there are nearly 10 different proposals under consideration in
the IETF, to deal with multihoming. Few are restricted to IPv4.
In other words, when there is a serious solution to multihoming -- ie,
being able to preserve a connection when using more than one IP
Address -- it will likely work for IPv4.
Most of these proposals are quite new. No more than a year old and
many less than 6 months.
This does not speak well for anything happening immediately, of
course. However quite a number of the proposals do not require any
significant infrastructure change. This bodes well for rapid
deployment, once they make it through the standards process.
On the other hand, getting the IETF to produce standards track
specifications out of this large pack of candidates could take another
