About this network

A Danish bank's seven prefixes, with three different netname conventions across them.

What it's used for

• Corporate and banking connectivity. 9,472 addresses in seven IPv4 prefixes with three observed BGP neighbours and no IPv6 announced.

Notable

• Four blocks share netname DK-DDB-990628, a date written YYMMDD.
• 185.218.228.0/22 is DK-DDB-20170824, the same scheme with a four-digit year.
• 212.93.56.0/24 is DK-DDB-8273492, where the trailing number is not a date at all.
• 193.111.64.0/23 breaks the pattern entirely with netname SAMNETS.
• None of the eighteen sampled addresses returned a reverse name.

Interesting

• Three conventions in one inventory is twenty years of registry practice in a single company's records. The 990628 block predates the change that made everyone spell years in full, the 2017 block follows it, and 8273492 is somebody's internal ticket or account number arriving where a date was expected.
• DDB is Den Danske Bank, the older form of the name that the legal entity still carries even though the business trades as Danske Bank. Registry records preserve the version of a name that was current when the paperwork was signed.
• SAMNETS reads as a shared or joint network, the sort of name given to space used with somebody else rather than by the bank alone.
