cable dsl isp residential

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.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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 1,768 prefixes, as published 2026-10-12. 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.
