Summary

KTT Carrier

United Kingdom · AI-generated

transit carrier ipv6

ESTRONET is the AS handle for KTT Carrier Limited.

What it's used for

  • The space carries global internet traffic, with the sole announced IPv6 prefix 2a07:54c6::/32 and zero announced IPv4 prefixes.
  • With 1 announced IPv6 prefix and 3 observed neighbours, the low address-to-neighbour ratio indicates a transit or carrier role rather than an access network.
  • As a worldwide carrier of internet traffic, the traffic from this AS consists of intercontinental transit and peering flows.

Notable

  • The registry holder is KTT Carrier Limited, matching the AS handle ESTRONET and the company name.
  • KTT Carrier operates as a global internet carrier, enabling communications between continents.
  • The address inventory consists of a single /32 IPv6 block with no IPv4 space announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 436 networks and 1,771 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.
