Disabling things so the log messages stop and you can pretend all the brokenness has magically gone away is indeed the easiest solution sometimes. It's rarely a good one, particularly for the long term. Anyway, the OP actually uses IPv6 on his network, so this is pretty much akin to suggesting that he turn off his computer to keep people from bothering it. The log messages are from his DNS server; he uses it for resolving and some local stuff; the log entries are the result of queries from random machines being rejected; random machines are doing that since at least one of his parent nameservers is handing out the IPv6 address of his server against his wishes; eventually he'll realize this is actually the case; and maybe he'll be able to convince whomever runs the parent nameserver(s) to update the records for his zone.
