I'm guessing some sort of location registration (at least specifying the country) is required for any public numeric IP address and tried ARIN since I believe this router is in Seattle. ARIN only showed me that the router belongs to a company in New York.

Here's a supposedly better website, but that showed many countries, and made me think that there might be no official registration needed (maybe such websites are using connected geolocation data, so I'm really getting the location of the users which most use this IP address?). So, I'm thinking that the New York company address from ARIN is the most I can confidently know.

Is there a reliable way to find the physical location of this ISP/router's hardware is really in Seattle? Is this not legally registered somewhere?

There is no legal requirement to register the location of an IP address, it is up to the owner of the block where IP addresses reside, and they can move them as needed.

However, there are plenty of registries that track such things. While an individual IP address may not be recorded in terms of location, the major routers around the world have their locations understood, and if you get to an IP via a hop from a router which you know the location of, you can surmise that the IP you are targetting is in the vicinity.

traceroute (or tracert) can help illuminiate this, it will tell you the names of the routers that you pass through to get to your destination.

In this case, it appears that the router is very likely in Seattle, and its name suggests it is too - my next hop before it is in Japan, which suggests this is a pretty core router:

Another tool you can use is a Visual Traceroute tool online, which attempts to show the path across the planet to get to an IP

Try https://www.iplocation.net/?query=206.132.169.217

The accuracy of the results depends on a number of providers of the "GeoIP" data.
