About this network

Ten prefixes, six netnames, and four blocks whose only registered party is an abuse address.

What it's used for

• A Russian regional access network. 5,632 addresses across ten IPv4 prefixes, one IPv6 prefix 2001:678:68c::/48, and thirteen observed BGP neighbours.

Notable

• Netnames include DELTA-TELESYSTEMS-NET, RU-DELTA-TELESYSTEMS-20220104, RU-SIBTEL-20040226, SIBTEL, SIBTEL-NETWORK, PALCOMNET and TECHNO-NET.
• Four /24s list Abuse-C Role as their sole registrant, with no organisation named at all.
• One /21 is registered to a named individual rather than a company.
• Sampled names split into .dynamic. and .static. branches, as in 188-0-42-0.dynamic.deltatelesystems.ru and 91-206-16-128.static.deltatelesystems.ru.

Interesting

• Six netnames across ten blocks, four of them naming companies that are not the holder, is an acquisition trail written into the registry. Each label is a fossil of whoever received that block, and the current operator inherited all of them rather than renaming anything.
• The blocks whose only contact is an abuse role have degraded as far as a record can go while remaining valid. The one thing left is where to send complaints, which is the one thing the registry actually enforces.
• Separating dynamic and static addresses in the DNS names tells anyone reading a log which kind of address they are looking at, without asking the operator. Networks elsewhere in this range publish no such distinction.
