As I understand it, you have to be careful mixing TSIG keys and IP
addresses within an ACL, as it's "first match wins"

So if you have a key and an IP listed in the same ACL - then anyone with
the key (from any IP), or anyone from that IP (without the key) will match
the ACL, which is unlikely to be what you wanted (presumably you actually
wanted "from this IP, with this key" to be the only matching case)

You can either use the approach you initially suggested, or try and use the
sort of approach listed here:
http://serverfault.com/questions/376578/bind9-combining-key-and-acl-for-allow-update

It's been a while since I've looked at ACLs though, so if the situation has
changed in more modern versions of bind I'd be very appreciative if people
could point me towards the appropriate docs :)
