PROMAX-AS is operated by Przedsiebiorstwo "PROMAX" Spolka Jawna Zofia Formanek-Okroj, Wieslaw Okroj.

What it's used for

  • The address space carries static IP addresses for end-users, as evidenced by reverse DNS entries such as static-ip-77-89-95-255.promax.media.pl and static-ip-194-106-214-128.promax.media.pl.
  • The AS announces 31232 IPv4 addresses across 6 prefixes, with 8 observed routing neighbours. This ratio of address space to peering partners indicates an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes match the AS holder, specifically Przedsiebiorstwo "PROMAX" Spolka Jawna Zofia Formanek-Okroj, Wieslaw Okroj and the Promax Admin Team.
  • The address inventory consists of six distinct IPv4 blocks, including larger allocations like 77.89.64.0/18 and 87.248.64.0/19, alongside smaller /22 and /23 blocks.
  • The netnames PL-PROMAX and PROMAX-MEDIA-NET reflect the operator's historical focus on media and telecommunications services in Poland.

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: 431 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.
