United States of America · AI-generated

hosting colocation voip

The AS handle CRITICALHOSTING-USA is held by Critical Hosting Solutions LLC.

What it's used for

  • The address space carries infrastructure for a cloud service provider, with netnames CH-MO-DC and CRITICAL-REASSIGNMENT3 indicating data center and reassignment blocks.
  • The AS announces 1280 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a hosting or colocation role rather than transit.
  • Traffic from this AS consists of hosted servers, desktops, email, websites, VoIP phone systems, and disaster recovery services for business clients.

Notable

  • Registrants include Critical Hosting Solutions LLC and Critical Hosting, Inc., which align with the announcer identity.
  • The address inventory is small and subdivided, consistent with an internal corporate estate for a specialized hosting provider.

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 1,781 prefixes, as published 2026-10-16. 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.
