It looks like Cambodia may be soon getting its own root domain name server (DNS server).
According to the APNIC whois database they have recently assigned an IP address range to Internet Systems Consortium (ISC) for running an F-root domain name server in Cambodia.
If this materializes, it is a very positive development for Cambodian internet community and users. It will reduce the amount of DNS queries that need to be sent through international circuits to other root name servers outside of Cambodia. This will improve speed for end-users as well as reduce the international bandwidth loads of Cambodian internet service providers.
Hopefully all Cambodian ISPs will set up a local peering circuit to the new f-root server!
