About this network

DCT-ASN belongs to DCT Technologies, Inc., a small technology and internet-hosting company in Green Bay, Wisconsin. It has held the number since 1996.

What it's used for

DCT originates a single /20, 66.18.16.0/20, and takes transit from TDS Telecom. Reverse DNS across the block is dominated by hosting and mail infrastructure: web1.hostmail.com, load balancers, name servers, virtual machines, and per-customer mail hosts such as mail.<customer>.com. The company also trades as Digital Magic Interactive.

Notable

This is a hosting network rather than an eyeball one. The address space is used for shared web and email hosting and for customer-facing servers, not for broadband subscribers, and much of it is sub-let to other small hosting brands whose names appear in the reverse DNS.

At roughly 4,096 addresses it is a genuinely small operator holding a genuinely old AS number, which is a common pattern among the mid-1990s ARIN registrations.
