I was always under the impression that the Knot 1.x config format only
allowed one IP address per remote definition. In fact, this is the
reason I have remotes defined thus:

remotes {
  master0-v4 {
    address IPv4;
    key KEY;
  master0-v6 {
    address IPv6;
    key KEY;

And then I use the "groups" directive to group these related masters

groups {
  master0 { master0-v4, master0-v6 }

Finally, I can use the "master0" name in the zone config to tell Knot
which masters to transfer from.

This is a rather cumbersome and convoluted way to define remotes in Knot
1.x, but it works for us. I am glad that the version 2 config format has
made this easy.

A key name is just a DNS label. So it works the same with or without the
final dot. The case of the key name also does not matter. The knot1to2
utility is just lowercasing the name and canonicalising it with a final
dot. It will just continue to work.
