About this network

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 -Z suffix from a legacy-records cleanup; that is a registry housekeeping artifact, not a change of holder.
