Summary

Orange Polska

Poland · AI-generated

cdn residential business

CPOP Content PoP is operated by Orange Polska Spolka Akcyjna.

What it's used for

  • The address space carries content delivery and residential access traffic, evidenced by the netnames OPL-CDN and PL-IDEA-DSL and reverse DNS entries like public100352.xdsl.centertel.pl.
  • The AS announces 24,576 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 8 observed neighbours, a ratio that indicates a regional access and content network rather than a transit provider.

Notable

  • Registrants for the announced prefixes include PTK-Centertel and OPL - Hostmaster, which align with the Orange Polska entity following the historical integration of Centertel.
  • The inventory consists of two distinct IPv4 blocks: a /18 for CDN services and a /19 for DSL access, alongside a single /36 IPv6 prefix.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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.
