About this network

The netname carries the AS number, and the reverse names mix two separators.

What it's used for

• A telephone cooperative's network. A single IPv4 /23 and one IPv6 /40 announced from the United States, through one observed BGP neighbour.

Notable

• The netname is the cooperative's name, this AS number written out in full, and the block's first address, so the label ties the allocation to the routing identifier.
• The AS handle is three initials and the word lab, which names a purpose rather than the organisation.
• Both answering addresses write the first two octets with dots and join the last two with a hyphen, under a domain belonging to none of the parties on record.
• Three addresses were queried for reverse DNS and two returned a name.
• The IPv6 allocation is large where the IPv4 block is small.

Interesting

• Mixing dots and a hyphen inside one address is the strangest separator choice in this range. Each half is a sensible convention; together they mean no single rule parses the name.
• A handle naming a lab suggests this number was registered for testing and kept in service, which is a common way small operators end up with more AS numbers than they planned.
• A fourth domain answering for the cooperative's addresses points at a shared operations arrangement between small carriers, the same pattern seen elsewhere in this range.
