business backup cloud enterprise

What it's used for
- The address space carries corporate infrastructure, with netnames such as
ACRON-3and registrants explicitly listed asAcronis. - The AS announces 9,472 IPv4 addresses across 18 prefixes and 6 IPv6 prefixes, while maintaining 40 observed neighbours; this ratio indicates a business network with significant peering requirements rather than a transit provider.

199.83.244.0/22,199.193.156.0/22,162.244.6.0/23,164.152.124.0/23,206.188.216.0/23, and216.245.154.0/23) agree with the announcer, identifyingAcronisas the holder. - The inventory includes prefixes registered to
Private CustomerandInternet Utilities NA LLC, suggesting a mix of directly allocated and leased or acquired address space. - The address inventory is finely subdivided into multiple /22, /23, and /24 blocks, consistent with an internal corporate estate segmented by site or service.

Reputation
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
