AS12041 — AS-AFILIAS1

Network type: hosting

AS12041 announces 150 IPv4 prefixes covering 119,296 addresses and 135 IPv6 prefixes.

About this network

Afilias ran the registry back end for a large share of the domain name system, including .info and the technical operation of .org, before being absorbed into Identity Digital.

What it's used for

• Authoritative and anycast DNS for top-level domain registries, plus the registry systems that sit behind them.

Notable

• The IPv6 space is the giveaway. The announcements sit in 2001:500::/xx — the range IANA set aside for root and TLD nameserver operators — across blocks like 2001:500:b::/48 and 2001:500:16::/47. That is not general hosting space; it is name server space.
• 159 IPv4 prefixes and 140 IPv6 prefixes for only 119,000 addresses, most of them /22s and /23s. Anycast DNS looks exactly like this: many small prefixes announced from many places at once, so the address count stays low while the prefix count climbs.
• 79 observed BGP neighbours. An anycast operator wants to be as few hops as possible from everyone, so it peers widely rather than buying transit from a couple of carriers.

Interesting

• Every block traces back to Afilias under AFILIAS-NET netnames even though the company itself no longer exists under that name, having been bought by Donuts in 2020 and folded into what is now Identity Digital. The registry paperwork outlives the brand.
