Nacionalinis Telekomunikaciju Tinklas
mobile isp lithuania
The AS handle NTT-LT-AS is operated by Nacionalinis Telekomunikaciju Tinklas (NTT), a Lithuanian telecommunications provider.
What it's used for
- The address space carries mobile and data services, evidenced by netnames such as
NTT_VOIP_NET,NTT_DATA_ZIRZILE_NET, andNTT_DATA_RETAIL_NET. - The AS announces 21,504 IPv4 addresses and 18 IPv6 prefixes, maintaining 120 observed neighbours. This high neighbour count relative to the address inventory indicates a role focused on transit and peering rather than a large-scale residential access network.
Notable
- Registrants include UAB Nacionalinis Telekomunikaciju Tinklas and UAB ZIRZILE, with the latter holding specific data blocks like
84.32.120.0/22. - The address inventory is finely subdivided into 42 IPv4 prefixes, including multiple /22 and /23 blocks, suggesting internal segmentation for different service types or customer segments.

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: 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.
