AS16158 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

The handle names a company that no longer exists, and the netname misspells the one that does.

What it's used for

• A telecoms software company's network. Two IPv4 prefixes announced from Israel, no IPv6, five hundred and twelve addresses, across five observed BGP neighbours.

Notable

• The AS handle is an entirely different company name from the holder field, the predecessor brand that this business was assembled from.
• One netname is a country code, the current brand with two letters transposed, and a date from the early nineteen-nineties, which makes it one of the oldest registrations in this range.
• The transposition means the netname spells the company's name wrong in a field that cannot be edited casually, and it has stayed wrong for three decades.
• The other netname is a town name and a four-digit number, a form that reads as a street address rather than a network label, on a block registered to staff and an abuse role without the company name.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Telecoms software firms merge constantly, and each merger leaves the previous name somewhere it cannot be reached. A handle is close to permanent once other people's configurations reference it.
• A netname naming a town on the other side of the world from the announcing country is the fingerprint of a headquarters move. The addresses stayed where they were assigned; the company did not.
