AS8444 HENDERSON

Janus Henderson Administration UK Limited (HENDERSON) — the UK arm of Janus

Henderson, the global asset manager. The registered address on the address space

is 201 Bishopsgate, London.

What it's used for

• Corporate IT for an investment-management firm. The AS announces a handful of /24s carved out of a legacy 144.2.128.0/20 assignment; there is no public rDNS and no customer-facing service on the space.

Notable

• A name trap: HENDERSON is a common surname and place name, and reads like a person or a town. It is the fund manager formerly known as Henderson Global Investors, which merged with Janus Capital in 2017.
• Enterprise space, not hosting or eyeball. Roughly 2,000 addresses, a few BGP neighbours, no downstreams.
• The 144.2.128.0/20 is RIPE legacy space — an early ARIN-era assignment later administered by the RIPE NCC — so the addresses are older than the current corporate name by some margin.

Interesting

• Financial firms in the City of London commonly run their own AS purely to multihome trading and market-data connectivity, which is why an asset manager appears in the routing table at all despite serving no internet users.
