Zone Transfers

We have now added Zone Transfer data to our ippages.com lookup service, but only to our HTML interface at this point. "Zones" are also known as "Subdomains", and typically represent the prefix names that are defined in front of a host name, as for example the "xml" in xml.ippages.com would be a "zone" if it pointed to it's own IP Address. In DNS terms, this is an "A" record.

What we recently discovered is that some host names have zone transfer data available to anyone who asks for it, so in these cases we are now showing it as part of the IP Address Lookup data. Try http://www.ippages.com/?domain=emachines.com to see an example (although if emachines.com becomes aware of this they will likely re-configure their name servers, and you will no longer be able to see their zone data).

showmyip.com will get this capability sometime later this month, and eventually our other IP Address lookup interfaces will as well.
