SYNCHRONOSSandIE-SNCR-20250408associated with Synchronoss Technologies and Synchronoss Software Ireland, Ltd. - The inventory consists of 1024 IPv4 addresses across 4 prefixes and 3 IPv6 prefixes, with only 2 observed neighbours, indicating a small-scale internal or business network rather than a transit provider.
Notable
- Registrants largely align with the announcer, including Synchronoss Technologies and Synchronoss Software Ireland, Ltd, though one prefix is registered to NewBay Software Inc.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 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.
