Summary
1-IX EU
transit exchange poland
The AS handle IXP-1-IX-EU is held by A-Systems Sp. z o.o.
What it's used for
- The space carries internet exchange and transit infrastructure, indicated by the netname
A-Systems-NETand the registrantHEAD; 1-IX EU Abuse Role. - With 256 IPv4 addresses announced across 1 prefix and 306 observed neighbours, the high neighbour-to-address ratio indicates a transit or exchange role rather than an access network.
- Traffic from this AS consists of peering sessions and transit routes for the 1-IX EU internet exchange, facilitating connectivity between networks in Europe.
Notable
- The registrant
HEAD; 1-IX EU Abuse Rolealigns with the announcer identity, confirming the space is operated by the exchange entity. - The address inventory is a single /24 block (185.239.27.0/24), which is a compact footprint typical for exchange infrastructure rather than a large ISP estate.
- Reverse DNS entries point to
euroline.com.ua, suggesting the specific IP range may be associated with or leased from a Ukrainian provider, though the AS is registered in Poland.

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 1,769 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.
