AS12772 — ENFORTA-AS Enforta Autonomous System

AS12772 announces 89 IPv4 prefixes covering 120,064 addresses and 0 IPv6 prefixes.

About this network

120,064 addresses in 103 prefixes, one neighbour, and an acquired brand still on the AS.

What it's used for

• A Russian business-connectivity network. 120,064 addresses across 103 IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• The AS handle is ENFORTA-AS, while the registered holder is JSC "ER-Telecom Holding".
• Every netname retrieved is of the form RU-RAID-, dated 20050707, 20070726, 20080618, 20090423 and 20100816.
• The largest blocks are the /19s 79.122.160.0, 94.28.64.0 and 188.133.160.0.
• One RDAP lookup, for 46.52.160.0/21, failed.
• Eighteen addresses were sampled and none returned a name.

Interesting

• The holder here also holds AS12768 in this same range, and both announce large subscriber networks through exactly one neighbour each. That is what a group looks like after buying its competitors: the acquired networks keep their own AS numbers and their own address blocks, and each one hangs off the parent's backbone rather than off the open internet.
• Enforta is the name of the business that was bought, and it survives in the AS handle because renaming an autonomous system means asking every other operator to update filters and route objects. The registry holder field gets corrected; the handle rarely does.
• Netnames dated across five years, from 2005 to 2010, in one inventory show address space accumulated allocation by allocation while the network grew, rather than assigned in a block.
