COLLINIGROUP is operated by FlashStart Group SRL.
What it's used for
- The address space carries corporate infrastructure for a web content filtering provider, evidenced by the netname
IT-COLLINIGROUP-20171211and reverse DNS entries pointing toflashstart.com. - The AS announces 1280 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with 15 observed neighbours, indicating a business network with moderate peering relationships rather than a large-scale access or transit provider.
- Traffic from this AS consists of web/API endpoints and filtering services, as FlashStart Group provides Web Content Filtering software and related enterprise solutions.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
9 upstream, 0 downstream and 13 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
