Hi all,
We are migrating our TKNet network to AMPRNet addressing. For machines
directly connected to Internet (ie : XLX, DMR), we are using
44.190.11.0/24 range. Those addresses are geo-located in Chicago. This
has funny consequences. F/ex, when doing speed tests with online
services such as nperf.com, the automatically-selected "nearest" server
is very far from here :-)
I have absolutely no idea about how geolocation works. Just for
curiosity, where is this information taken from ? The Whois database ?
But Brian's address is in San Diego, not in Chicago...
Is there an easy way to change geo-location information for a specific
AMPR subnet ?
Thank you in advance. 73 de TK1BI

There is no one true source. Thats one of the reasons the information is not terribly
accurate.
One of the big providers of geolocation data however is MaxMind - probably partially
because you can get much of the info for free. You can lookup IPs on their website and
submit corrections (though I think there is some verification required so I don’t know if
they accept all updates).
Other people have their own databases though so even if MaxMind update theirs it’s no
guarantee a particular service will notice.

Hi Andy,
Thank you for the info. I submitted a correction request to Maxmind,
giving this link as justification :
https://portal.ampr.org/networks.php?a=region&id=3302
Now, let's see what happens...
As you said, there seems to be several different databases. This one,
for example, geo-locates our addresses more accurately in Paris (which
is the place where our BGP announcement is made)

With TCP/IP over meteor scatter, this may be doable, HI :-)

This one is a little bit more interesting and complete. It returns data
from 3 different GeoIP databases. One locates us in France, another one
in the US, and the third in Norway.
https://www.iplocation.net/
None of them seem to provide a correction request form, anyway...

We are in the same boat as our isp will not do bgp over vdsl although its stable except
when the fibre caboney gets smashed by under age drivers lol
tried the updates dodnt work. As i use our bgp in cairns, melbourne and sydney we are at
the luck of the dice to a correct value

If you have delegated reverse DNS, one could publish DNS LOC records:
1.11.190.44.in-addr.arpa. IN LOC 42 N 42 W
see, for optional precision/elevation parameters:
https://en.wikipedia.org/wiki/LOC_record
https://tools.ietf.org/html/rfc1876
Whether or not the forward/reverse records are consumed by the various
third-party Geo-IP sites remains to be seen, but under the guise of
amateur radio, it might make sense to *experiment*, try, and
report back.
...Perhaps even with a proposal that all networks/IP addresses under
44.0/8.415 MAY or SHOULD provide LOC records. Thus opening things up
to a bit of data analysis---perhaps something CAIDA would be
interested in?

I'm planning to deploy internal DNS servers, for direct and reverse
lookups. Then, I'll be able to add LOC records. But as far as public DNS
servers have some security concerns, and I have no experience about
that, DNS server has been delayed to later ;-)

In my experience, some of them use
[maxmind](https://www.maxmind.com/en/home), as the widely used geoip was
built upon a free version from them. You can correct them at their
[site](https://support.maxmind.com/geoip-data-correction-request/).
As for the sites behind Cloudflare, they can get two letter location
code from the CloudFlare. Other CDNs may have their own version.
As for the Google overlord, they have their own GeoIP db, unfortunately
it's next to impossible to change GeoIP for them. Yes, I know they have
a webform where you can submit correction data to them, but for me it
never worked. To update your GeoIP for Google you will need to register
at their [Peering Portal](https://peering.google.com), wait for
approval, and wait another weeks for your update to take effect.
I think the easiest and quickest way is to announce the prefix by
yourself. It looks most GeoIP databases are built from ASN whois and/or
country lists on RIRs.

Currently, I'm announcing 44.190.11.0/24 by myself via a Vultr VPS
located in Paris. It's interesting to see I have several kinds of
geolocation results :
- In San Diego, California (not too bad, this is the WHOIS address of Brian)
- In Chicago (which seems to be the headquarters of Choopa, the company
who owns my VPS provider Vultr)
- In Paris (the most clever one, which probably recognised that my BGP
announcements are made from a data center in Paris)
- In Norway (this one just shows how inaccurate and unreliable GeoIP can
be, HI )

Actually, Vultr.com (Choopa) offices are in Matawan, NJ, near New York City. But it
doesn’t really matter. They seem to do an outstanding job regardless of the data center
chosen.
