Summary

PTTNET

Philippines · AI-generated

telecom isp residential business

PTTNET is the autonomous system for Philippine Telegraph and Telephone Corporation.

What it's used for

  • The address space carries netnames explicitly labeled PTTNET and registrants identified as Philippine Telegraph and Telephone Corporation IP Network.
  • The AS announces 10240 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, with 13 observed neighbours, indicating a role as a national access and transit provider.

Notable

  • Registrants for the majority of prefixes align with the announcer, listing IRT-PTT-PH and Philippine Telegraph and Telephone Corporation.
  • The address inventory is mixed, including blocks registered to Cloud Innovation Ltd and several prefixes with unknown registrants, suggesting a combination of owned and leased or third-party space.
  • The inventory includes a diverse range of prefix sizes, from /21s to /24s, within the 203.160.0.0/16 and 45.x.x.x ranges.

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 1,775 prefixes, as published 2026-10-11. 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.
