Thanks for that too, Jason. Simple command, which is yet so powerful. So long
Web-based tools, which thus far I have used for DNS lookup and reverse DNS
lookup.
It seems to work in both directions:
roy@BAINE:~> getent hosts www.ukfsn.org
217.158.120.136 www.ukfsn.org
roy@BAINE:~> getent hosts 130.88.190.250
130.88.190.250 cg250a.halls.manchester.ac.uk
