Unclassified RIPE Content
Summary
CriticalCase
hosting colocation italy
The AS handle CRITICALCASE is held by CriticalCase s.r.l.
What it's used for
- The address space carries hosting and colocation infrastructure, evidenced by reverse DNS entries such as
fwcc.myserverfarm.itandcs-176-221-53-254.to2.ccws.it. - The network announces 11,008 IPv4 addresses across 17 prefixes with only 3 observed neighbours, a ratio that indicates a hosting or content provider rather than a transit carrier.
- Traffic from this AS consists of web servers, API endpoints, and colocation customer infrastructure, consistent with the operator's business as a High Availability service provider.
Notable
- Registrants for the majority of prefixes are CriticalCase s.r.l, while some blocks, such as
185.6.72.0/22and91.212.167.0/24, are registered to Upprovider Srl. - The address inventory is fragmented into 17 distinct prefixes, including several /24s and /23s, suggesting a history of incremental acquisitions or internal segmentation.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,784 prefixes, as published 2026-10-19. 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.
