But if the guest is going to choose an IP address itself rather than
getting one from DHCP, it should know that it's choosing an address on
the correct network, and I don't like the idea of depending on qemu's
current choice of default network/host IP/dns IP to remain constant.
That's fair enough, although it seems unlikely it would change
especially as no one is really touching the SLIRP code beyond urgent
security fixes.
However I'm not clear if when you said "address should be mandatory"
you meant the network address or the guest DHCP start address. It
seemed to me you meant the DHCP start address, but now I think perhaps
you meant the network address?
