Largest networks in Northern Mariana Islands

The operators holding the most IPv4 address space that geolocates to Northern Mariana Islands, from the same data that answers a lookup.

IPv4 only — mixing in IPv6 would make any address count meaningless, since a single IPv6 block can hold more addresses than the entire IPv4 internet. Ranked by where networks are observed, which is not always where they are registered.

How accurate is geolocation in Northern Mariana Islands?

Country-level accuracy is reliable — the address blocks allocated to networks operating in Northern Mariana Islands are well documented by the regional registry. City-level accuracy is not a guarantee anywhere: an address is mapped to where its network announces it, which is often a provider hub rather than the user's suburb.

Every response carries an accuracyRadius in kilometres. Treat the coordinates as the centre of a circle that size, not as a pin. Mobile and corporate connections in Northern Mariana Islands routinely resolve to a different city entirely, and anyone on a VPN will resolve wherever the exit node sits.
