Summary
Tennet Telecom
isp residential telecom romania
The AS handle TENNET-AS is held by Tennet Telecom SRL.
What it's used for
- The address space carries residential customer traffic, evidenced by reverse DNS entries such as
client-89-47-96-128.proinet.roand netnames likeRO-TENNET-20051129andPROINET-LINK-TELECOMUNICATII-SRL. - The network announces 7424 IPv4 addresses across 16 prefixes and 1 IPv6 prefix, while maintaining 29 observed neighbours, a ratio consistent with an access or eyeball network providing last-mile connectivity.
- Traffic from this AS consists of subscriber eyeballs for residential broadband services in Romania, including DSL and fibre connections managed by Tennet Telecom and its associated entities.
Notable
- Registrants align with the announcer, primarily listing Tennet Telecom SRL, with some prefixes registered to Tennet Link SRL and Proinet Link Telecomunicatii SRL, indicating internal segmentation or historical acquisitions.
- The address inventory is finely subdivided into multiple /24 and /23 blocks, reflecting a site-by-site or customer-segmented corporate estate rather than a single large contiguous allocation.

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 1,773 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.
