About this network

UNISYS-AS-C is a second autonomous system belonging to Unisys Corporation, the American IT services and enterprise-computing firm, alongside AS6071.

What it's used for

• Part of Unisys's own corporate routing and the infrastructure behind its managed-services and outsourcing contracts.
• It originates a small amount of Unisys-registered address space; the bulk of the company's IPv4 footprint is announced from its sibling AS.

Notable

• Enterprise addressing — corporate offices, data centres and hosted client systems — rather than an ISP or hosting product sold to the public.
• The -C and -E suffixes distinguish the two Unisys autonomous systems; they are routing divisions of one company, not separate business units with different purposes.

Interesting

• ARIN registered AS6071 and AS6072 to Unisys on the same day in November 1995, part of a sequential run of genuine mid-1990s allocations.
