  Today is day of memories

  used a patched tinydns
  http://code.google.com/p/geoip-tinydns/

  I downloaded the ASN / ROUTE databases from arin and RIR to build some specialized distribution of streamings to optimize costs... Was a really fun project..

  Just as an example this is an extract of the route db databases from ripe

  
  route:          193.254.30.0/24
  descr:          Lufthansa Airplus Servicekarten GmbH
  origin:         AS12726

  route:        212.166.64.0/19
  descr:        Tiscali Spain
  origin:       AS12321

  source:       RIPE
  

  I parsed all the route object and built a distribution map based on the peeering bgp available at each edge streaming site...

  The produced map file was a veeery long list like this

  %peer-diretti:151.10.0.0:16:fms:
  %peer-diretti:192.104.23.0:24:fms:

  were %peer-diretti was a geo location based on the route object and fms the dns name to be mapped...

  I personally prefer server side methods to GeoDNS (provided it's not a CDN).

  Use Maxmind's free GeoIP country database and redirect based on location to a specific subdomain. us.example.com, uk.example.com, de.example.com etc.

  There are many ways to achieve this. F5 Global Traffic Managers are one way which load balances traffic to other F5's or just a plain server. Based on any number of metrics. Maybe some of the open source load balancers can do something similar.

  @kbar what are exactly your needs? Maybe nginx with the geoip (maxmind) database module is all you need...
