Summary
MNSi Telecom (Managed Network Systems)
isp legacy
MANAGEDNETWORK is Managed Network Systems Inc., which trades as MNSi Telecom, an independent Canadian ISP based in Windsor, Ontario. The ASN was registered with ARIN in 1996.
What it's used for
- Retail internet access in southwestern Ontario. Reverse DNS across the announced space is overwhelmingly
dyn<address>.HSIA.mnsi.net— dynamic high-speed-internet-access subscriber pools, the unambiguous signature of an eyeball network. - A small amount of the space carries router and peering infrastructure names instead, including gateway interfaces dedicated to content-cache offload.
Notable
- This is a genuinely small operator running a large-ish address footprint, around 170,000 IPv4 addresses spread over about ten prefixes. Independent ISPs that have been around since the mid-1990s often hold more space per subscriber than newer entrants.
- The ARIN org handle carries the
-Zsuffix from a legacy-records cleanup; that is a registry housekeeping artifact, not a change of holder.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
