About this network

One reverse name has the lookup zone glued onto the end of it, a missing dot published to the internet.

What it's used for

• A managed connectivity network. Twenty IPv4 prefixes announced from Canada, no IPv6, fifteen thousand six hundred and sixteen addresses, through two observed BGP neighbours.

Notable

• Three company names appear: the handle carries an older brand with two extra letters and the abbreviation for an autonomous system number, the holder is a second company, and almost every block belongs to a third, spelled three different ways.
• Most netnames are that older brand cut one letter short of its own spelling, followed by a numeral two. One names a three-letter airport code and the word for a subnet. One joins the newer brand to a mineral and a two-letter code.
• Three of eighteen queried addresses answered, on the older brand's domain, each labelled with a three-letter airport code for its city.
• One is the word for a network, on the network's own first address. One names a router, a port and a security zone.
• The third is the word for the last address in a block, the brand's domain, and then the entire reverse lookup zone appended after it.

Interesting

• A reverse name ending in the lookup zone is a zone file missing one trailing dot. The software treated a finished name as a fragment and helpfully completed it.
• The mistake is invisible to anyone who never asks, which is why it survives. Nothing breaks; the answer is just wrong in a way only a reader notices.
