Originally, textual IPv4 addresses were maintained centrally
by ISI as a file format of HOSTS.TXT, when there was no DNS
and users are required to download the current most HOSTS.TXT
from ISI through ftp.

At that time, there can be, because of consistent central
management, just one way to represent them, which is described
in rfc810 as:

    <address> ::= <octet> "." <octet> "." <octet> "." <octet>
    <octet> ::= <0 to 255 decimal>

Obviously, syntax was extended, at least beyond decimal, by a
BSD implementation with language C.
