Similar idea to HOSTS.TXT. Periodic download and munge. More interestingly though, NRS used the opposite ordering to DNS, so "cs.nott.ac.uk" was "uk.ac.nott.cs", which became a problem when Czechoslovakia got their TLD (.cs) in the 80s as the both DNS and NRS were used in parallel for some period of time. I believe NRS was still being used to some capacity by the time Czechoslovakia split in 93. Aaron -- Aaron Jackson - M6PIU http://aaronsplace.co.uk/
