What did you do?
I tried to resolve hostname that contains special symbols, e.g. '/', '='. But I got error 'no such host'. Utilities host, dig and nslookup provides this opportunity. Also they allow to resolve hostnames with length is more then 255 symbols unlike net.LookupHost.
Example:
_, err := net.LookupHost("/.yandex.ru")
fmt.Println(err) // lookup /.yandex.ru: no such host
What did you expect to see?
For example, host:
$ host /.yandex.ru
/.yandex.ru has address 213.180.204.242
/.yandex.ru mail is handled by 10 not-for-mail.yandex.net.
