Unclassified RIPE
Summary
LambdaNetUA
isp residential ukraine cable
The AS handle LAMBDANETUA is operated by LAMBDA LLC.
What it's used for
- The address space carries residential access traffic, evidenced by reverse DNS entries such as
pppoe-128.lambda.net.uaandpppoe-255.lambda.net.ua. - The network announces 3072 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with 10 observed neighbours, indicating a role as an access provider rather than a transit carrier.
Notable
- All registrants for the announced prefixes are listed as LAMBDA LLC with the netname ORG-LL380-RIPE, consistent with the AS holder.
- The address inventory consists of three distinct IPv4 blocks in Ukraine, including a /21 and two /23s, alongside a single /48 IPv6 prefix.

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 1,783 prefixes, as published 2026-10-17. 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.
