SOUTHERNHILL is operated by SouthernHill BV.

What it's used for

  • The address space carries WAN and enterprise connectivity, evidenced by netnames like NL-SOUTHERNHILL and NL-IVENGI1, and reverse DNS entries such as sh-networks.net and ivengi.net.
  • The AS announces 6400 IPv4 addresses across 7 prefixes and 6 IPv6 prefixes, while maintaining only 3 observed neighbours, a ratio that indicates a local access or enterprise service provider rather than a transit hub.
  • Traffic consists of managed WAN services including Dark Fiber, Leased Lambda, Managed Ethernet, and IP-VPN, serving business clients requiring secure data transport and network solutions.

Notable

  • Registrants include SouthernHill Holding BV, SouthernHill BV, Ivengi Groep BV, and Ayelda BV, with netnames reflecting both the primary brand and acquired or related entities.
  • SouthernHill Holding BV is the primary registrant for the majority of the inventory, while Ivengi Groep BV and Ayelda BV hold specific blocks, suggesting a corporate structure involving multiple legal entities or acquisitions.
  • The inventory is composed of several /22 blocks and one /24, with IPv6 space allocated in /29 prefixes, indicating a standard enterprise ISP footprint.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
