... The labels must follow the rules for ARPANET host names. They must
start with a letter, end with a letter or digit, and have as interior
characters only letters, digits, and hyphen. There are also some
restrictions on the length. Labels must be 63 characters or less.

The start of the line gives the owner of the RR. If a line begins with
a blank, then the owner is assumed to be the same as that of the

names starting with the label "*". Such RRs are called wildcards.

... general strategy is to look for locally-available name server RRs,
starting at SNAME, then the parent domain name of SNAME, the

choices here; the best is to start parallel resolver processes looking
for the addresses ...

"(" to start a multi-line RR and ")" to show the end of a multi-line RR.

... The following examples illustrate the operations a resolver must perform
for its client. We assume that the resolver is starting without a
cache, as might be the case after system boot. We further assume that
the system is not one of the ...

A.ISI.EDU appears on this list as well as the previous one, but that is
purely coincidental. The resolver would again start transmitting and
waiting for responses. Eventually it would get an answer:
