Hungary · AI-generated

isp residential cable dsl

The AS handle NEXUM-AS Hungary is held by Nexum Hungary Internet Service Provider Ltd.

What it's used for

  • The space carries residential and business access traffic, evidenced by reverse DNS names like pool.internet-x.hu and pool.overnet.hu, and netnames such as HU-BEKESNET-20021009 and HU-OVERNET-20021009.
  • With 7168 IPv4 addresses announced across 7 prefixes and only 7 observed neighbours, the ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to Nexum Hungary Internet Service Provider Ltd., while two prefixes are registered to OverNet Kft.
  • The address inventory consists of blocks in the 213.157.96.0/21 range and a single /24 in 85.8.208.0/24, suggesting a consolidated regional footprint.

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.
