Summary

Synamedia

Israel · AI-generated

video business infrastructure

SYNAMEDIA-AS is operated by Synamedia Technologies Israel LTD.

What it's used for

  • The address space is registered under the netname Synamedia-NET and is associated with Synamedia, a provider of video infrastructure and experience solutions.
  • The AS announces 1024 IPv4 addresses within a single prefix (192.118.32.0/22) and has 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant Synamedia Technologies Israel LTD matches the registry holder and the AS handle, confirming consistent ownership.
  • Synamedia was formerly known as NDS Group Ltd. and later Cisco Videoscape, having been spun out from Cisco's SPVSS business.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
