AS12792 — CINET-AS Komsomolska str. 43

AS12792 announces 0 IPv4 prefixes covering 0 addresses and 77 IPv6 prefixes.

About this network

Zero IPv4 addresses and 77 IPv6 prefixes — an autonomous system that only exists in the newer protocol.

What it's used for

• IPv6-only routing from a Bulgarian holder. No IPv4 announced at all, 77 IPv6 prefixes, and two observed BGP neighbours.

Notable

• The IPv4 inventory is empty: 0 addresses, 0 prefixes.
• The IPv6 blocks include a ladder from 2a09:4040:1::/48 doubling through /47, /46, /45, /44, /43 and /42.
• One announcement, 2602:fed2:7910::/44, comes from a different registry's range entirely.
• The AS handle is CINET-AS Komsomolska str. 43.
• No addresses were sampled, because there is no IPv4 space to sample.

Interesting

• An AS with no IPv4 at all is rare enough to be worth stopping on. Almost every network holds some, because almost every service still needs it; announcing only IPv6 means the addresses behind this AS reach the old internet through somebody else's translation, or not at all.
• The doubling run of prefixes is one range expressed in CIDR, not seven allocations: each is twice the size of the last as the decomposition walks up to fill a block that is not a power of two. Seventy-seven announcements is what that arithmetic costs when it happens repeatedly.
• 2602: belongs to a different regional registry than the rest of this inventory, so one block was obtained through a completely separate membership. Address space does not have to come from the region an organisation sits in, and IPv6 makes that cheap enough to do casually.
• The AS handle carries a street address, the second in this range to do so.
