Summary
Ennwise
enterprise hosting legacy
ENNWISE-AS is Ennwise, a small managed-IT and hosting provider registered at 419 Main Street, Huntington Beach, California. Despite the low AS number, ARIN records the ASN as registered in February 2020 — this is reissued space, not an early-internet network.
What it's used for
- Ennwise sells managed service plans, security monitoring, cloud/infrastructure consulting and its own VPS hosting to businesses "from small teams to over 100 users". The AS carries that hosting estate plus the networks of a couple of managed customers.
- RIS sees 7 IPv4 prefixes / 1,792 addresses, 2 IPv6 prefixes, and only 2 observed neighbours. Two upstreams and under 2,000 addresses is a single-site provider, not a carrier — the neighbour count rules out any transit role.
Notable
- Most of the inventory is self-registered:
192.163.28.0/22and its more-specifics, plus23.136.44.0/24, all sit underENNWISE-NET-00/ Ennwise at ARIN. - Two prefixes are registered to third parties:
208.91.103.0/24to Signal Restoration Services (a large commercial property-damage restoration firm in Troy, Michigan) and165.140.252.0/24to Westrock Restoration LLC. On its face that resembles the leased-address-space pattern, but it does not hold up: both registrants are real, findable operating companies in the same industry, everything is ARIN-only, and the space is announced by their IT provider. This is an MSP announcing customer blocks, which is normal. - The one sampled PTR,
managed-by.skylinkhosting.llc, points at hosting rather than end-user access, consistent with the VPS side of the business.
Interesting
- The customer pair suggests a vertical: two disaster-restoration contractors on the same small MSP's AS.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
