Summary

Synchronoss Technologies

Ireland · AI-generated

business messaging enterprise

The AS handle SNCR-ASN is held by Synchronoss Software Ireland, Ltd.

What it's used for

  • The address space carries corporate infrastructure, with netnames SYNCHRONOSS and SNCR-SMH indicating Synchronoss Messaging services.
  • The inventory consists of 9 IPv4 prefixes and 7 IPv6 prefixes, observed against 3 routing neighbours, indicating a small-scale enterprise network rather than a transit or access provider.
  • Traffic from this AS represents internal corporate endpoints and messaging platform infrastructure for Synchronoss Technologies.

Notable

  • Registrants include SYNCHRONOSS TECHNOLOGIES and NewBay Software Inc, reflecting the company's history of acquiring Openwave Messaging in 2016.
  • The address inventory is finely subdivided into /23 and /24 blocks, consistent with an internal corporate estate segmented by site or service.

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: 440 networks and 1,773 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.
