Hosting ARIN
Summary
Richweb, Inc.
hosting enterprise legacy
RICHWEB is Richweb, Inc., an IT services and hosting company operating out of the Richmond, Virginia area (offices in Ashland, VA) since the mid-1990s. It runs managed networks, private cloud hosting and colocation for businesses, schools and service providers in the mid-Atlantic.
What it's used for
Hosting and managed-network services rather than consumer access. RIS observes two IPv4 prefixes — 208.74.80.0/21 plus a more-specific 208.74.85.0/24 — totalling about 2,048 addresses, and one IPv6 prefix, 2602:f993::/36. Both v4 prefixes are registered to Richweb's own ARIN block (RICHWEB-IPV4), so the space is first-party and not leased in from a third party.
Three observed BGP neighbours puts this squarely in the small multihomed-provider bracket: enough upstreams for resilience under a hosting SLA, nowhere near the neighbour count of a transit carrier.
Notable
The IPv6 allocation is a /36, which is a provider-sized block rather than an end-site /48 — consistent with a company that sub-delegates address space to hosted customers and downstream networks rather than just numbering its own office LAN.
No PTRs came back on the four addresses sampled, but that is a sample and not a finding — nothing should be read into it either way.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,771 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
