About this network

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-NET and the registrant HEAD; 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 Role aligns 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.
