Comment (by teor):

 Ideally, I'd like to see the following:
 * accept6/reject6 means IPv6 only, accept6 *:* means all IPv6 addresses,
 warn on IPv4 address or *4

 In addition, we could:
 * introduce accept4/reject4, which mean IPv4 only, accept4 *:* means all
 IPv4 addresses, warn on IPv6 address or *6
 * deprecate accept/reject, which mean IPv4 and IPv6, accept *:* means all
 IPv4 and IPv6 addresses, warn on all uses and recommend user moves to
 accept4/accept6/reject4/reject6

 I think this provides a sensible migration path and I'm happy to code it
 (I'm familiar with the code in question).

 What do you think, nickm?
 Which parts would you want in 027? Would you want any of it in 026?
