Unclassified APNIC
Summary
Duna
business poland small
DUNA-AS is operated by Przedsiebiorstwo Produkcyjno-Uslugowo-Handlowe 'Duna' Dunaj Piotr.
What it's used for
- The address space is registered under the netname
PL-DUNAfor the holder, indicating a corporate or business allocation rather than a public ISP or transit provider. - The AS announces a single IPv4 prefix,
83.151.32.0/20, comprising 4096 addresses, with no IPv6 prefixes in inventory. - With only 4 observed neighbours in RIS, the low neighbour count relative to the address block suggests a small-scale access or internal network rather than a transit hub.
Notable
- The RDAP registrant matches the AS holder exactly, confirming direct ownership of the announced space.
- The address inventory consists of a single contiguous /20 block, which is a standard size for small business or site-specific allocations.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
