AS34525 KOBA-AS Polish ISP
Unclassified RIPE Cable/DSL/ISP
Summary
KoBa
isp residential cable dsl
The AS handle KOBA-AS is operated by KoBa Sp. z o.o., a regional telecommunications provider in Poland.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to
koba.plandpiasta.pldomains. - The network announces 22,272 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, while maintaining 44 observed routing neighbours. This ratio of address space to peering partners is consistent with an access or eyeball network rather than a transit provider.
Notable
- All registrants for the announced prefixes are listed as
KoBa NSD ContactorKOBA Sp. z o.o., aligning perfectly with the AS holder. - The address inventory is composed of multiple distinct blocks, including a large /19 and several smaller /20, /21, and /22 allocations, reflecting a consolidated corporate estate.
- The operator is identified in secondary sources as a wired telecommunications carrier based in Bialystok, operating in the Cable/DSL/ISP sector.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
