 Note that a subdomain name that exceeds 64 characters is not actually
 allowed by standards.

 https://en.wikipedia.org/wiki/Domain_Name_System#Domain_name_syntax,_internationalization

 > A domain name consists of one or more parts, technically called labels,
 that are conventionally concatenated, and delimited by dots, such as
 example.com.
 > ...
 > A label may contain zero to 63 characters, because the length is only
 allowed to take 6 bits.
