About this network
Some reverse names quote a range these addresses do not belong to.
What it's used for
- A national carrier's regional branch. Twelve IPv4 prefixes announced from the Russian Federation, no IPv6, fifteen thousand addresses, across five observed BGP neighbours.
Notable
- Reverse names put the last octet first, then a label built from the word for network and the address's own leading octets, then a city domain: 254.net-94.242.149.kaluga.ru.
- Two answering addresses break that rule. The address 109.225.32.128 answers with 128.net-94.242.32.kaluga.ru, naming a range it is not in, and the neighbouring block does the same.
- One block uses a shorter form with only the third octet, so three naming schemes coexist in one zone.
- Eight of the twelve blocks share a single netname written in capitals with an underscore, describing a regional centre; the other four use the parent company's code and an allocation date.
- Eighteen addresses were queried for reverse DNS and seven returned a name.
Interesting
- Those mismatched names are a template copied to a new range and never edited. Anyone using reverse DNS to work out where an address sits would be sent to the wrong network.
- Twelve routes ranging from a /19 down to five separate /24 blocks is a network assembled from whatever was available, over years, rather than planned.
- No IPv6 at all from a branch of a national carrier is the gap worth naming here.
