Server operators are volunteers who offer a route to the well known addresses of the AS112 servers, either to handle the queries generated by their local user populations, or to help carry the global traffic load. We intend the list of operators shown below to be complete and accurate, but that may not be possible. For example, the F root server operator also runs instances of AS112 servers at certain sites as does Afilias. Also, some Internet Exchange Points (IXPs) run AS112 servers within their network only, making them invisible to the wider Internet. Some of these sites are listed here too.
Contrast this with periodic surveys taken of the net for hidden AS112 survers:
To be added to this list, please send email to ops -at- as112.net.
AS112 operators are also asked to subscribe to the mailing list described elsewhere on this website. Note that publicly accessible statistics are very definitely encouraged. The DSC package is ideal for this.
Finally, AS112 operators are reminded about the importance of gathering statistics using one of the tools discussed.
Note: this list is really a best efforts endeavour, as the final list at time of writing is not by any means either definitive or complete.
