Summary

Bhutan Telecom

Bhutan · AI-generated

telecom residential mobile isp

BTTELECOM-AS-AP is operated by Bhutan Telecom Ltd.

What it's used for

  • The address space carries customer-facing traffic, evidenced by reverse DNS entries such as 45-64-249-126.swr.druknet.bt and 45-64-250-64.host.druknet.bt.
  • The network announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • Registrants for both announced prefixes (45.64.248.0/23 and 45.64.250.0/24) are listed as Bhutan Telecom Ltd, matching the AS holder.
  • Bhutan Telecom Ltd was established on July 1, 2000, as a fully state-owned company following the corporatization of the erstwhile Department of Telecommunications.
  • The inventory consists of two small IPv4 blocks with no announced IPv6 prefixes.

Reputation

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
