MAXIMUMA-AS is operated by Maximum-Net LLC.

What it's used for

  • The address space carries residential and business internet access, evidenced by netnames such as MAXIMUMA4-NET, MAXIMUMA2-NET, and UA-MAXIMUM-20170413 registered to Maximum-Net LLC.
  • The AS announces 28,672 IPv4 addresses across 11 prefixes and 3 IPv6 prefixes, while maintaining 122 observed routing neighbours.
  • As a cable and DSL provider in Ukraine, the traffic consists primarily of subscriber eyeballs accessing the internet via fixed-line connections.

Notable

  • Most registrants align with the announcer, with Maximum-Net LLC holding the majority of prefixes; however, 194.187.30.0/23 is registered to SMART-M SOLUTIONS LLC, and 64.240.77.0/24 and 71.5.40.0/24 are registered to CenturyLink Communications, LLC and Hosting.com, Inc. respectively.
  • The inventory includes a mix of large blocks like 178.158.192.0/18 and smaller /24 allocations, with some prefixes showing legacy registrants from other organizations.

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 1,771 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.
