RFC 1035 specifies (among other things) two requirements for DNS packet transport and parsing:
All DNS packet parsers must accept compressed packets
DNS packets sent over UDP cannot be larger than 512 bytes
Supporting compression is optional on the packet building side, but not supporting it often results in packets larger than 512 bytes. Long domains and domains with lots of records are common, so not supporting compression often results in DNS packet corruption when using UDP because most DNS implementations (including the one in this package) will only read the first 512 bytes.
