AS16525 — KBR

AS16525 announces 6 IPv4 prefixes covering 4,608 addresses and 0 IPv6 prefixes.

About this network

The holder is three initials; the netname spells out the three surnames they came from, plus a suffix the company dropped.

What it's used for

• An engineering and services company's network. Six IPv4 prefixes announced from the United States, no IPv6, four thousand six hundred and eight addresses, through three observed BGP neighbours.

Notable

• The holder and the registrant on every block are the same three capital letters, with no expansion given anywhere.
• Every block carries the same netname, and it is those three initials written out in full as three hyphenated names, with the corporate suffix on the end. The joining symbol between two of them is gone.
• All six blocks come from one parent range at four different sizes, and they are scattered through it rather than adjacent, so none can be merged.
• The AS handle is the initials again, matching the holder and not the netname.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A company that renamed itself to its own initials leaves the expansion in exactly one place: the field nobody updates. The netname is a dictionary entry for the handle, preserved by inattention.
• Six fragments of one range, at four sizes, is what a network looks like when address space was requested as it was needed and never consolidated. Each fragment is a separate line in every routing table that carries it.
• Nothing in reverse DNS across four and a half thousand addresses is a network facing its own staff and its own contracts, not the public.
