About this network

The reverse names give the router, the line card, the port and the sub-interface.

What it's used for

• A national operator's infrastructure network. Nine IPv4 prefixes and four IPv6 prefixes announced from Ukraine, four thousand three hundred and fifty-two addresses, through a single observed BGP neighbour.

Notable

• One answering name is xe-11-1-1.2.at.mx03.iev4.core.as3326.net: an interface type with three numbers for its position in the chassis, a sub-interface number, a two-letter word, a router name with its own number, a site code, and the word for the network core.
• The other is lo0.rr1-ua-rtr.as3326.net, which names a loopback interface on a route reflector.
• Both sit on a domain built from a different AS number than this one, and the AS handle repeats that same different number twice.
• One netname names a third AS number that differs from the handle's by a single digit.
• The remaining netnames run to five conventions, including one written in mixed case where every other netname in the record is capitalised.
• One block's registry lookup failed, so its details are unknown rather than absent.
• Of eighteen addresses queried, two returned a name.

Interesting

• Interface-level reverse names exist so that a traceroute reads like a diagram, which is a gift to the engineer on call and to anyone mapping the network from outside. The chassis slot is genuinely useful and genuinely more than a stranger needs.
• A handle naming one AS number, a netname naming another, and the announcement coming from a third is three generations of numbering in one record.
