AS12683 announces 144 IPv4 prefixes covering 136,960 addresses and 0 IPv6 prefixes.

About this network

144 separate announcements reaching the rest of the Internet through three neighbours.

What it's used for

• Regional access for a branch of the Russian national incumbent. 136,960 addresses in 144 IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

• Most blocks carry the netname MacroregionalSouth, an internal division name rather than a place or a company.
• 82.119.128.0/19 is the exception, netname RU-RTK-20040217.
• The prefix sizes run from /19 down through /20, /21 and /22, with 119 further blocks below the twenty-five largest.
• Eighteen sampled addresses were queried and none returned a name.

Interesting

• 144 announcements against three neighbours is the shape of a branch network rather than an independent operator. A network that peers widely has a reason to advertise its pieces separately, because different neighbours should prefer different paths. With three upstreams, all 144 routes travel the same way, and the rest of the Internet carries 143 entries it could have collapsed into far fewer.
• Every router in the world stores those entries. The cost of splitting a network into pieces is paid by everyone else, which is why deaggregation on this scale is a recurring argument in operator forums and why filters exist that reject the smaller pieces outright.
• MacroregionalSouth is a corporate org chart written into the address registry. It tells a reader which internal division to chase and nothing at all about where the addresses are, which is the opposite of what a netname is usually good for.
