77 be compatible with most formats in common use.
78 It will first separate an address into 1 to 3 fields using a single delimiter
86 Each field is then examined for byte separators (colon or period).
87 If there are byte separators, each subfield separated is taken to be
88 a small hexadecimal number, and the entirety is taken as a network-byte-ordered
89 quantity to be zero extended in the high-network-order bytes.
90 Next, the field is inspected for hyphens, in which case
91 the field is assumed to be a number in decimal notation
92 with hyphens separating the millenia.
93 Next, the field is assumed to be a number:
95 as hexadecimal if there is a leading
100 (as in Mesa), or there are any super-decimal digits present.
101 It is interpreted as octal is there is a leading
103 and there are no super-octal digits.
104 Otherwise, it is converted as a decimal number.
