Re: Why are there no GeoDNS solutions anywhere in sight?

[Eric Adler <eaptech () gmail com>]

If this is for http and similar user-accessed (not machine accessed)
traffic, you could do what some large manufacturers and shipping companies
do: Provide a (relatively) low-bandwidth "Select where you are in the
world" global landing page which then redirects to a different
domain/subdomain for each region.  This also lets them direct relatively
localized content easily. For example, panasonic.com can list items sold
mass-market for the US, panasonic.nl for the Netherlands, and
panasonic.com.au for Australia.  Yes, you may well run into times that a
user in the US goes to the .au site because s/he wants to research an .au
product that isn't detailed on the US page but this is not the bulk of your
traffic (and, if through stats, you find it becomes so, you can work on
your design so that it isn't).
