Support for edns-client-subnet
It would be useful to support ECS - edns-clientsubnet in
knotd and kdig.
ECS is an edns extension that improves geolocation of dns clients by passing the client's ip to the authoritative dns server via a dns cache. Without ECS the authoritative server only sees the ip address of the cache.
There is a patch for BIND's
dig at http://wilmer.gaa.st/edns-client-subnet/.
There is an article about ECS at http://www.cdnplanet.com/blog/which-cdns-support-edns-client-subnet/.
Thanks for your consideration.
