isp residential poland access

PROINTERNET-AS is operated by Pro Internet Sp. z o.o., a telecommunications company based in Gdańsk, Poland.

What it's used for

  • The address space carries residential and access traffic, evidenced by reverse DNS entries such as rev.pro-internet.pl and rev.kosakowo.net.
  • The AS announces 11,264 IPv4 addresses across 3 prefixes and maintains 4 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes are listed as PRO INTERNET Sp. z o.o., matching the AS holder.
  • The address inventory consists of three distinct IPv4 blocks: 188.124.160.0/19, 46.231.152.0/21, and 185.112.116.0/22.
  • No IPv6 prefixes are currently announced in the inventory.

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.
