Summary

PTCL

Pakistan · AI-generated

telecom residential national isp

The AS handle PKTELECOM-AS-PK is held by Pakistan Telecommunication Company Limited.

What it's used for

  • The address space carries netnames PTCLBB-PK and PTCL, indicating broadband and general telecommunications services.
  • With 3,721,472 IPv4 addresses announced across 599 prefixes and 602 observed neighbours, the high neighbour count relative to the address inventory suggests a role involving significant transit or peering, consistent with a national telecommunications provider.

Notable

  • All sampled registrants align with the announcer, identified as Pakistan Telecommuication company limited (sic) under the IRT IRT-PTCLBB-PK.
  • The inventory is dominated by large /15 and /16 blocks in the 39.0.0.0/8 and 182.0.0.0/8 ranges, reflecting a substantial national address estate.

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.
