There are discussions starting within the Regional Internet Registries (RIRs) about the creation of trading market in IPv4 addresses as we approach the inevitable exhaustion of unallocated addresses. The view being put forward is basically "this is likely to happen anyway and by discussing it now, we can ensure it happens in an orderly way". When I first heard this idea I was a bit surprised. The RIRs are policy based bodies and so a shift to a trading market appears to be an abandonment of that policy base. However I have been partly corrected on that. ›››
If you want to find out the WHOIS server for a particular TLD then in many cases you can do it with a simple DNS lookup. Just query for an SRV record for the domain _nicname._tcp.tld, like this... Many other TLDs follow this convention including .au .at .dk .fr .de .hu .ie .li .lu .nl .no .re .si .se and .ch. ›››
