    Internet domain names are only loosely specified.  Section
    3.5 of RFC 1034 recommends a syntax (modified in Section
    2.1 of RFC 1123).  The pattern above is intended to allow
    for current practice in domain name use, and some possible
    future expansion.  It is designed to hold various types of
    domain names, including names used for A or AAAA records
    (host names) and other records, such as SRV records.  Note
    that Internet host names have a stricter syntax (described
    in RFC 952) than the DNS recommendations in RFCs 1034 and
    1123, and that systems that want to store host names in
    schema nodes using the domain-name type are recommended to
    adhere to this stricter standard to ensure interoperability.
    
    The encoding of DNS names in the DNS protocol is limited
    to 255 characters.  Since the encoding consists of labels
    prefixed by a length bytes and there is a trailing NULL
    byte, only 253 characters can appear in the textual dotted
    notation.
    
    Domain-name values use the US-ASCII encoding.  Their canonical
    format uses lowercase US-ASCII characters.  Internationalized
    domain names MUST be encoded in punycode as described in RFC
