isp residential dsl hungary

ZALASZAM-AS is operated by Zalaszam Informatika Kft.

What it's used for

  • The address space carries residential DSL traffic, evidenced by reverse DNS entries such as 0-114-69-119.dsl.pool.zalaszam.hu and 255-115-69-119.dsl.pool.zalaszam.hu.
  • The AS announces 2048 IPv4 addresses within a single /21 prefix and 1 IPv6 prefix, with 11 observed neighbours, indicating a regional access provider role.
  • Traffic consists of subscriber eyeballs for a local cable and DSL ISP serving the Zalaegerszeg region in Hungary.

Notable

  • The RDAP registrant Zalaszam Informatika Kft. matches the AS holder, confirming consistent ownership.
  • The inventory consists of a single contiguous IPv4 block and one IPv6 prefix, typical of a regional ISP managing its own customer base.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
