Is it possible to create different NS for different countries?
For example, we have 4 nameservers:
#for US
ns1.us.domain.com
ns2.us.domain.com
#for Europe
ns1.europa.domain.com
ns2.europa.domain.com
DNS requests coming from Europe will go to ns1.europa, ns2.europa
and requests from US and other world will go to ns1.us, ns2.us
.
Maybe some paid DNS provides can do it? Any other other ways to speedup DNS lookup? Any links and advises are appreciated.
