provider doesn't handle large zonefile results

If you implement DNS; you need to implement the entire spec. Either retry with TCP or set an EDNS0 option to allow larger replies.

@miekg any tips on how to do this?

If you have a dns.Client you can set udpsize https://godoc.org/github.com/miekg/dns#Client, but you still need to add an EDNS0 OPT record to the message you're sending https://godoc.org/github.com/miekg/dns#hdr-EDNS0 and https://godoc.org/github.com/miekg/dns#OPT.SetUDPSize

For retrying with TCP, you need to check the return if the msg has Truncated set and retry with dns.Client's Net set to "tcp"

Retrying with the EDNS0 option and with TCP were implemented as part of #35.
