Re: Digging to the final IP
If all you are after is one of the final IP addresses (not the entire set), then using a dumb client might be easier. For instance, 'ping'. $ ping -q -c1 www.google.com PING www.google.com (203.66.155.113): 56 data bytes If you want to get more than one IP address, then you'll need an intelligent client such as 'host' or 'dig: $ host www.google.com www.google.com has address 203.66.155.49 www.google.com has address 203.66.155.50 www.google.com has address 203.66.155.44 ... www.google.com has address 203.66.155.45 www.google.com has IPv6 address 2404:6800:4008:c03::67 On 10/20/14, 12:03 PM, Fajar A.

RE: Digging to the final IP
We’re using this in a bash shell script. I don’t think there’s a native shell command to get the IP, so I’ll use a mixture of host and dig as necessary. Thanks, Frank From: Fajar A.

Re: Digging to the final IP
Why do we need to have a option to dig to massage the results into
every possible different form?
dig A $name | awk '$0 ~ /status/ $0 !~ /status: NOERROR,/ {
sub(,, , $6 ); print $6; x=1
}
$4 == A { print $5; x=1 }
END { if (!x) print TIMEOUT }'

That feature runs on our system, but it doesn't digging through to a final IP or failure: getent ahosts mail.automatedwastesystems.net returns nothing.
