hosting business netherlands

H4HOSTING-AS is operated by H4Hosting BV.

What it's used for

  • The address space carries business hosting and internet access, evidenced by reverse DNS entries such as hosted-by.as51050.net, fiber.nexxtcom.nl, and share-mta26.embluenet.com.
  • The AS announces 7,168 IPv4 addresses and 2 IPv6 prefixes, with 47 observed neighbours. This ratio of address space to peering relationships indicates a hosting and business access provider rather than a large-scale residential ISP or transit carrier.
  • Traffic from this AS consists of web and API endpoints, VoIP media, and branch backhaul for business clients, consistent with H4Hosting's provision of internet access and hosting services for the business market.

Notable

  • Registrants for the majority of prefixes are H4Hosting BV, while two prefixes (193.38.140.0/23 and 193.39.6.0/23) are registered to NexxtCom B.V., indicating leased or acquired address space.
  • The address inventory is subdivided into seven IPv4 prefixes, including two /21 blocks and five smaller /22 and /23 blocks, reflecting a segmented corporate estate.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
