About this network

A retired carrier brand still sitting in the netname of a live block.

What it's used for

• An engineering consultancy's network. Two IPv4 blocks announced from the United States, no IPv6, and two observed BGP neighbours.

Notable

• One block is registered to a carrier under the netname UUNET63, a brand that has not been the operator's name for a long time.
• The registry lookup for the other block failed, so nothing can be said about who holds it.
• The AS handle is the holder's surname alone, with no counter or suffix.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Netnames outlive the companies that coined them. This one names a network that was folded into a larger carrier, and then that carrier into another, and the string survived both because nothing in the registry forces a rename when ownership changes. It is a reliable dating marker and an unreliable ownership signal.
• The trailing digits on that netname are a range marker rather than a counter for this customer, so the same string appears on many unrelated blocks.
• Announcing carrier space rather than its own is the ordinary arrangement for a firm whose business is not networks. It also means the address space does not move if the firm changes supplier.
• With one of two lookups failed, half this record's ownership picture is simply unknown, which is a different thing from being empty.
