About this network

Corporate ASN (NTTDATA-SERVICES-AS2) of NTT DATA Services Holdings Corporation, the North American IT services arm of Japan's NTT DATA.

What it's used for

• Enterprise and IT-outsourcing networking for NTT DATA's Americas business: corporate sites, delivery centres, and managed-services infrastructure run on behalf of client organisations.
• Announces a modest block of legacy IPv4 space rather than eyeball or consumer-facing address space.

Notable

• This is a business network, not a public ISP: address space here maps to offices, service-delivery environments, and hosted client workloads rather than to subscribers.
• The NTT DATA Services business is the former Dell Services organisation, which in turn was Perot Systems before Dell acquired it. NTT DATA bought the unit from Dell in 2016, so the address space predates the current name.

Interesting

• The handle and organisation have changed hands more than once while the AS number stayed put, a common pattern in the low-numbered ARIN space where the network outlives the brand on the paperwork.
