About this network

HCN-01 is operated by ELLINIKA DIKTIA KALODION MEPE, commonly known as HCN.

What it's used for

• The address space carries residential broadband traffic, evidenced by reverse DNS entries such as dhcp-188-117-235-254.cm.hcn.gr and pon25597.cpe.hcn.gr.
• The AS announces 14,848 IPv4 addresses across 9 prefixes while maintaining only 5 observed neighbours, a ratio characteristic of an access network rather than a transit provider.
• Traffic consists of subscriber eyeballs for cable and DSL services, with reverse DNS indicating both DHCP-assigned addresses and Point-to-Point Protocol over Ethernet (PON) customer premises equipment.

Notable

• Registrants are mixed: JM-DATA GmbH and JM-DATA Telekom GmbH hold several prefixes (e.g., 188.117.224.0/20, 37.98.192.0/21), while ELLINIKA DIKTIA KALODION MEPE and m-gruppe GmbH & Co. KG hold others (e.g., 188.117.192.0/21, 213.108.88.0/21).
• The inventory is fragmented across multiple registrants, with netnames like AT-JM-DATA-20090618 and HCN-Net-01 reflecting different allocation histories or leased space.
