[GTER] DNS Reverso (complemento)

[MARLON BORBA]

"The Concise Guide to DNS and BIND", Nicolai Langfeldt, Que Books, p. 245:

 "RFC 952 defines hostnames as consisting of the letters A-Z, the numbers 0-9, the minus sign or dash (-) and the period. Periods are allowed as delimiters only in domain style names. The first character must be a letter, and the last character can't be a - or a period. It also does not allow single-character names. RFC 1035 recommends following RFC 952 for hostname strings."

"RFC 1123 changes one rule. It allows a digit as the first character."

[]s,

Marlon.
