About this network

A company named after the routing table's catch-all entry, running one /24 and one IPv6 block.

What it's used for

• A small network operator. 256 addresses in the single IPv4 prefix 74.120.12.0/24, the IPv6 block 2607:ff08::/32, and two observed BGP neighbours.

Notable

• The company, the AS handle and the netname all read DEFAULTROUTE, after the entry a router uses when nothing more specific matches.
• The IPv6 block is a /32, the size a registry gives an operator rather than a customer.
• One of three sampled addresses answered, and the name belongs to another company's mail server.
• The registrant matches the AS holder.

Interesting

• Naming a company after the default route is a joke aimed at the few thousand people who would get it, and it has the practical effect that the firm's name appears in every routing discussion by accident.
• A /32 of IPv6 against a single /24 of IPv4 is the ratio the address transition was supposed to produce everywhere. Here the operator holds far more IPv6 than it can plausibly use and the smallest possible amount of the scarce kind.
• The one hostname visible belongs to a customer rather than the operator, which is the usual outcome when a hosting company names nothing of its own and its tenants name everything of theirs.
