I just tried out removal of bind-utils on a soon to be retired machine. It seems fine with the caveat that we lose /bin/host and /bin/dig
Perhaps a perl script might suffice to emulate 'host' on machines that might need the occasional networking debug session. Just typed this up, so FWIW:
use Net::DNS;
my $res = Net::DNS::Resolver->new();
my $sought = $ARGV[0];
my $a_query = $res->search($sought);
if ($a_query) {
foreach my $rr ($a_query->answer) {
if( $rr->type eq 'A' ){
printf("%s has address %s\n", $sought, $rr->address);
} elsif( $rr->type eq 'CNAME' ){
printf("%s is an alias for %s\n", $sought, $rr->cname);
$sought = $rr->cname;
}
}
} else {
warn "Unable to obtain a record for $ARGV[0]: ", $res->errorstring, "\n";
}

Are you running sssd? Are you connected to the AD?
