Unclassified ARIN Enterprise
Summary
Accretive Networks
enterprise legacy
Autonomous System 4258 (ATG-4258) is registered to Accretive Networks, the network arm of Accretive Technology Group, a Seattle-based technology company.
What it's used for
- Carries traffic for the company's own consumer internet platforms rather than selling connectivity to third parties.
- Peers openly at internet exchanges in North America, which is typical of a content operator that wants to hand traffic directly to eyeball networks.
Notable
- Content and enterprise address space: an IP here is company infrastructure, not a residential subscriber.
- Accretive operates several AS numbers alongside this one; AS4258 is the low-numbered legacy member of that set, dating to the mid-1990s.

Reputation
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 1,852 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.
