Research direction

No files or tests are named. Start by reading RFC 6891, then trace the existing DNS message and UDP/TCP transport paths. Done means EDNS0 supports DNS messages larger than 512 bytes over UDP while preserving the existing TCP alternative, with coverage for the new behavior.

Description

help wanted new feature

We should add support for extended DNS (EDNS0) to support DNS messages larger than 512 bytes over UDP (#12) as an alternative to requiring transport via TCP (#47).

See https://tools.ietf.org/html/rfc6891 (and older https://tools.ietf.org/html/rfc2671)

I'm not working on this at the moment, but figured it's worth posting this here anyway. In case anybody feels like picking this up, PRs would be much appreciated +1
