So, I have a site in London. We recently changed from PA space to PI space.
I SWIP'd the new space 155.33.8.0/23 to reflect our London location.


You might want to try adding an RFC 8805/9092 Geofeed to your ARIN WHOIS comments. If you're not sure what this means, 
see the example for Cloudflare at <https://whois.arin.net/rest/ip/172.64.0.0>, which contains:

Comment: Geofeed: https://api.cloudflare.com/local-ip-ranges.csv

In theory, geolocation providers can see that and use it to publish accurate info without guessing. (I have no idea 
whether Apple uses it.)
