Summary

Interspace

Israel · AI-generated

hosting business israel

The AS handle INTERSPACE-AS is operated by Interspace Ltd., an Israeli telecommunications and hosting provider.

What it's used for

  • The address space carries hosting and cloud infrastructure, evidenced by netnames such as ISERVER-VERTICAL1 and Interspace-Cloud.
  • Reverse DNS entries like sdip-34-254.dips.intervision.co.il indicate the space also supports dynamic IP services for end-users or specific client segments.
  • With 9,728 IPv4 addresses announced across 16 prefixes and only 4 observed neighbours, the network functions as a destination for hosted services rather than a transit provider.

Notable

  • Registrants consistently identify as INTERSPACE NOC or Interspace Ltd., aligning with the AS holder.
  • The inventory consists of 16 IPv4 prefixes with no IPv6 announcements, reflecting a legacy IPv4-centric estate.
  • The address space is finely subdivided into /22, /23, and /24 blocks, typical of a corporate or hosting environment managing distinct service verticals.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 445 networks and 1,817 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.
