So you think you know about domain name service (DNS) records?


Jan Schaumann has cataloged all 100 resource record types in github in a blog entry, and within the live zone files for his domain  panix.netmeister.org.  So you can query his DNS server for documentation about record types.  Clever.

$ dig +short aaaa aaaa.dns.netmeister.org.
2001:470:30:84:e276:63ff:fe72:3900
$ dig +short txt aaaa.dns.netmeister.org.
"Format: single a hexadecimal IPv6 address"
"A 128-bit IPv6 host address. RFC1884 (1995); RFC4291 (2006)"
