About this network

One block's netname says it is for testing, and it is announced to the world like any other.

What it's used for

• A bank's network. Five IPv4 prefixes and one IPv6 /48 announced from the Russian Federation, three thousand addresses, across four observed BGP neighbours.

Notable

• One block is named with a two-letter contraction of the bank followed by the word test, and it is in the routing table alongside the rest.
• Another is named for a common service with a sequence number; a third names a payment system in mixed case; the remaining two share the country code, the bank and an allocation date.
• Every block lists the same informal contact, a role named as the bank's technology crew.
• Answering addresses put all four octets in reverse order after the word host, under the bank's own domain.
• One answering address is a numbered gateway on a different domain, spelled with a hyphen and a different suffix from the bank's main one.
• Fifteen addresses were queried for reverse DNS and five returned a name.

Interesting

• Test space in the global routing table is worth noticing. Whatever is in that block is reachable from everywhere, and its name says nobody expected it to be treated as production.
• Two domains for one bank, one of them holding the network equipment, splits the infrastructure away from the brand customers know. That is either tidy separation or a leftover.
• The holder name carries quotation marks around the bank's name, copied straight out of a company registration document into a routing record.
