About this network

STAFFORDNET is Stafford Associates Computer Specialists, Inc., a long-established Long Island IT company in East Setauket, New York. It runs a certified data centre alongside a managed-services and web-development business: colocation, managed servers, offsite backup and disaster recovery, plus web design and hosting for local clients.

What it's used for

• Hosting and managed infrastructure for customers of that data centre, and the company's own network. The reverse DNS shows both halves at once: most sampled addresses carry the operator's own generic naming (5.130.11.66.staffordnet.com, and a router named rtr7206a.staffordnet.com), while one resolves to www.timecreations.com — a customer's website living directly in the AS. Space that carries third-party web presences is hosting space.
• RIS sees 12 IPv4 prefixes / 3,072 addresses, no IPv6, and 7 observed neighbours. Twelve contiguous /24s and seven peers is a small regional provider: enough upstreams to stay reachable, far too little space to be an eyeball ISP or a carrier.

Notable

• The 66.11.128.0–66.11.140.0 /24s are all ARIN-registered as STAFFORDNET-BLK-1 to Stafford Associates itself. RDAP lookups failed on the 216.168.129/130/135 /24s, which is a failed query and not a clearance — nothing about those three is established either way.
• The rDNS naming convention is reversed-octet (133.140.11.66.staffordnet.com), an older style that fits a network that has been carrying customers for a long time.

Interesting

• The handle reads like a network operator, and in a limited sense it is one, but the company behind it sells cabling, fibre splicing, PC repair and eCommerce development as readily as it sells rack space. The AS is the infrastructure end of a full-service local IT shop.
