AS15953 — AS_KBCGS_CEDC

AS15953 announces 2 IPv4 prefixes covering 6,144 addresses and 1 IPv6 prefixes.

About this network

The first registrant is a registry handle rather than a name, and the netname date falls in the early nineteen-nineties.

What it's used for

• A banking group's shared services network. Two IPv4 prefixes and one IPv6 /47 announced from Belgium, six thousand one hundred and forty-four addresses, through a single observed BGP neighbour.

Notable

• Both blocks share a netname of a country code, the group's name, and the date 19921020, which is among the earliest in this range.
• The first entry in the registrant list is a registry object identifier, four letters, a digit and the registry's own suffix, rather than a person or a company.
• The AS handle is built with underscores instead of hyphens, joining the letters for an autonomous system, a contraction of the group with its services arm, and a four-letter code for something the record never expands.
• The IPv6 prefix is a /47, an odd size that is two adjacent site-sized ranges treated as one announcement.
• The routing archive first saw this number three years after the numbers around it.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• A registry handle in a name field is what happens when a record is edited through the raw interface rather than a form: the handle is what the database actually stores, and the human-readable name is the thing that has to be looked up.
• Address space dating from the early nineteen-nineties on a banking group means the network predates the group's own internet presence by years.
