Afilias operates DNS for many TLDs/ccTLDs.
Peering requests can be sent to: peering@afilias-nst.info

Please configure 200 or higher as max-prefixes for both IPv4 and IPv6 and accept prefixes up to /24 and /48 respectively for best results.

Please note that due to the nature of our service (anycast DNS) we are not able to aggregate down further, in case you are wondering why you are seeing many /24 and /48 prefixes from us.
