That's fine, as long as the destination is addressable within a subnet. If the destination does not live on a subnet, why not use a host route (i.e., /128 address)? > -I would avoid the assumption that an ad-hoc router maintains a > stable IP address while moving around. Then you will have trouble. There is no free lunch. Either: (a) the IP address stays the same, and the routes change, or (b) the IP address changes, and there is a resolver to associate the IP address with some other identifier. Since the design of the resolver in (b) is an unknown and arguably much more difficult, I'll take (a) with a great sigh of relief. > > > The churning aspect of host-based routes was just one argument against > /128s and finally against loopback/virtual interfaces.

I must have missed that, sorry.

Well, to me it did sound very negative. Moreover, I think it is just fine to pass around subnet prefixes, if you have subnets. Regards, Charlie P.
