AS15084 — CONVERGYS - Concentrix CVG Corporation

AS15084 announces 22 IPv4 prefixes covering 10,496 addresses and 1 IPv6 prefixes.

About this network

The AS handle still carries the company's previous name.

What it's used for

• A business-services network. Twenty-three IPv4 prefixes and one IPv6 prefix announced from the United States, with twenty-five observed BGP neighbours.

Notable

• The AS handle is CONVERGYS while every other field names the holder as Concentrix, so the handle preserves an identity the rest of the record has moved on from.
• The netnames encode the first two octets of the blocks they sit on, as CONCENTRIX-167-1 and CONCENTRIX-206-126, and each is reused across several prefixes in that range.
• One announced block is registered under the netname APNIC-AP to the regional registry itself rather than to any operator.
• Regional subsidiaries appear under their own netnames, one naming a Philippines entity and one an India entity under a netname that keeps an acquired company's name.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Twenty-five upstreams for ten thousand addresses is an unusual ratio. Most holders in this range with that little space have two or three. A contact-centre operator needs its sites reachable from wherever its clients are, and the neighbour count is the only field that shows it.
• The stale handle is the useful part for anyone matching records by name: the AS registry and the address registry disagree about what this company is called, and both are current.
