Summary

National Telecommunication Corporation

Pakistan · AI-generated

telecom isp pakistan nsp

NTC-AS-AP is operated by National Telecommunication Corporation.

What it's used for

  • The address space is registered under netnames NTCISP-PK and NTCPKNET, with reverse DNS pointing to reverse.ntc.net.pk, indicating a telecommunications service provider.
  • The AS announces 24,320 IPv4 addresses across 14 prefixes and 11 IPv6 prefixes, while maintaining only 3 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.

Notable

  • All registrants in the evidence pack are consistent with the announcer, listing National Telecommunication Corporation as the administrator and IRT contact.
  • The address inventory is heavily concentrated in the 175.107.0.0/16 range, with multiple /20, /21, /22, and /23 blocks, alongside smaller allocations in 202.83.160.0/20, 113.197.48.0/21, 43.250.84.0/22, and 103.253.156.0/22.

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 1,783 prefixes, as published 2026-10-17. 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.
