About this network

NYLI-AS is the corporate network of New York Life Insurance Company, the large mutual life insurer headquartered at 51 Madison Avenue in Manhattan.

What it's used for

• Enterprise networking for New York Life: head office, data centres, agency offices and the company's public-facing web and policyholder systems.
• Announces about 8,000 addresses, all drawn from 206.210.0.0/19 — a single contiguous legacy block sliced into /24s.

Notable

• Reverse DNS resolves to newyorklife.com hostnames such as mdl.giving.newyorklife.com — named corporate services, with no subscriber or hosting addressing anywhere in the block.
• A financial institution running its own AS is usually about control and multi-homing: keeping customer-facing systems reachable through more than one carrier without depending on any single provider's address space.

Interesting

• The AS was registered with ARIN in 1996, when relatively few non-technology corporations bothered to take an autonomous system of their own.
