logging

I have an issue which I believe is caused by incorrect DNS queries (doubled subdomains like _record.host.subdomain.tld.subdomain.tld) when querying for SRV records.

So I need to an alternate DNS server with heavy logging so I can see every query (especially stupid ones), acting as a recursive resolver with the ability create records which override real DNS records so I can not only find the records it's (wrongly) looking for, but populate those records as well.

I know I could install a DNS server on yet another linux box, but I feel like this is the sort of thing that someone may already setup a simple python script or single use vm just for this purpose.
