Re: Apple Support Geolocation Jon Lewis via NANOG (Oct 08)
Are you kidding? "back in August" as in a month or two ago? We're still
dealing with stale IP Geo data for IP space acquired and swipped years
ago.

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.)

AS13509 announces it before, but it is an APNIC ASN? It was announced by
mistake or it belonged to APNIC and was transferred to ARIN for some reason?

I see, following my reply I was approved for ARIN WhoWas for
historic WHOIS, however it seems like they only support singular
IP address lookups. I have followed up with their support to see
if I can see the history of a /16 block.

Best,

most recent ARIN issued report

[arin-issued] Daily Report for 2025-10-07

Add 131.143.16.0-131.143.19.255
through
Add 131.143.235.0-131.143.235.255

131.143.0.0/16 was issued to Rockwell so its easy to see that there
could be blocks that existed globally.

NetRange: 131.143.124.0 - 131.143.124.255

I noticed that the ARIN Waiting List has recently decreased quite a bit.
Then I found that a new company I’ve been following, along with several
others, has received newly allocated IPs from this same range. The
allocations might not cover the entire /16 block, but these new IP
assignments don’t appear in ARIN’s cleared IPv4 blocks list

zgx,

Have you checked out
https://stat.ripe.net/resource/131.143.0.0-131.143.207.255#tab=database
yet? it has some nice graphs showing all the historical
announcements from that range. Sadly the page takes forever to
load due to the size.

However, I failed to find the 131.143.0.0/16 range from the ARIN
"Cleared for Waiting List" CSV, may I ask how you found that
range?

btw, i'd recommend signing up for...

ARIN Waiting List Recipients Begin Receiving Allocated IPs from 131.143.0.0/16 Zhang Gaoxing via NANOG (Oct 08)
Hello,

I have noticed that the number of people on the ARIN Waiting List has been
decreasing significantly recently, and some have started receiving IP
allocations from the 131.143.0.0/16 range. I also found that these IPs were
previously geolocated in Switzerland. Were these addresses reclaimed from
an organisation? I’m curious about the origin of these IPs.

I'm not too sure how often scheduled updates generally occur, but I would
hope in the order of days, not weeks or months.

Good luck,

Re: Apple Support Geolocation Adam Blackington via NANOG (Oct 08)
They may use an internal tool.

Re: Apple Support Geolocation Stephen Griffin via NANOG (Oct 08)
I found "Maxstack" also was wrong. So, we SWIP'd back in August, is this
typical for them to be so wrong for so long? I have folks complaining about
being geoblocked to BBC as well... :(

Re: Apple Support Geolocation Stephen Griffin via NANOG (Oct 08)
Is odd that they still do, we SWIP'd a while ago, but I filled out the
form. Will see what happens.

Re: Apple Support Geolocation Steve Miller via NANOG (Oct 08)
Maybe they happen to be using ipapi?

https://ipapi.co/

Only mentioning it because that looks like the only major geoop db that
still lists that block as Boston.
