I've had some Apple devices get seriously confused by their location services and I'm trying to provide strong hints.
It would also be nice to prime WiFi 6 Certified WAPs with their locations based on LOC RR's since we happen to have convenient infrastructure to do exactly that.
Thanks.

<p>LOC RR's are not currently very popular. But I have some where
they provide different locations from geolocation services based
on IP address. Google, for one, reports the city from the LOC
record in preference to data associated with the IP address. I
haven't looked recently, but last time I looked, the geolocation
services' use of LOC was spotty. Some used LOC, other's didn't.
For them, it's pretty cheap to mine WHOIS and address block
assignments; doing a DNS lookup for each address (and walking up
the tree on a miss) gets expensive fairly fast.<br>

<p>There are some concerns with overly precise LOC records - great
if you want a shopper to to show up at your store, perhaps less so
if you run a shelter or secure facility. I've been known to
intentionally misplace LOC records so that they're good enough for
routing, census, and other coarse applications, but not accurate
enough for navigation.</p>
<p>With respect to part 2: You might also consider that GPS
receivers are cheap (every cellphone has one) and retail USB
receivers are easily found at less than $20. This may be a better
choice than LOC records. GPS tells you where you are; LOC tells
everyone else...<br>
