IDN and Private RR in Go DNS

Sun, 21 Sep 2014 19:45:00 +0000

Thanks to the excellent work from Alex Sergeyev, Go DNS has gotten some new features. I want to highlight two: IDN (https://www.ietf.org/rfc/rfc3492.txt) and Private RR support (http://tools.ietf.org/html/rfc6895).

IDN

This adds support for converting from and to Punycode. There is no explicit support, you will need to call idn.ToPunycode and idn.FromPunyCode yourself if you are dealing with IDNs.

The examples give in the code:

name := "インターネット.テスト"
fmt.Printf("%s -> %s", name, idn.ToPunycode(name))

Which outputs:
