Name space definitions: Domain names in messages are expressed in terms of a sequence of labels. Each label is represented as a one octet length field followed by that number of octets. Since every domain name ends with the null label of the root, a domain name is terminated by a length byte of zero. The high order two bits of every length octet must be zero, and the remaining six bits of the length field limit the label to 63 octets or less. To simplify implementations, the total length of a domain name (i.e., label octets and label length octets) is restricted to 255 octets or less. Therefore the max length of a domain name is actually 253 ASCII bytes without the trailing null byte or the leading length byte, and the max length of a label is 63 bytes without the leading length byte. z@^((?![-])[-A-Z\d]{1,63}(?JJKK K 1D#.. 1/00 0ZZ\\ "(**-@%"H"H!::lA66c|jS)7 The FQDN as a string in absolute form )absoluters r__str__z FQDN.__str__1s }rc~|js tjn tj}t j|tjSN)rrPREFERRED_NAME_SYNTAX_REGEXSTRALLOW_UNDERSCORES_REGEXSTRrecompile IGNORECASE)rregexstrs r_regexz FQDN._regex7s8* 1D / /0  z(BM222rct|j}|jdr|dz}|dkrdS|j|j}|sdS|j|jkS)a True for a validated fully-qualified domain nam (FQDN), in full compliance with RFC 1035, and the "preferred form" specified in RFC 3686 s. 2, whether relative or absolute. https://tools.ietf.org/html/rfc3696#section-2 https://tools.ietf.org/html/rfc1035 If and only if the FQDN ends with a dot (in place of the RFC1035 trailing null byte), it may have a total length of 254 bytes, still it must be less than 253 bytes. .F)lenrendswithr*match labels_countr)rlength regex_passs ris_validz FQDN.is_valid@suTZ :  s # #  aKF C<<5[&&tz22  5 D$444rcj|jddk}|jd|rdndz}|S)Nr,rr-)rcount)rhas_terminal_dotr8s rr2zFQDN.labels_countYs<:b>S0   %%.>)EAF rcD|jdo|jS)z True for a fully-qualified domain name (FQDN) that is RFC preferred-form compliant and ends with a `.`.
