Internet Protocol version 6 (IPv6) is the future of Internet and soon all the domains will switch to it. Many Governments OR ISP’s has already implemented IPv6 in their countries and reasons. All the Operating Systems which are coming in market by default supports IPv6. Microsoft Windows Vista, 7 and 2008 server editions also supports IPv6 but recently while working on one Windows 2008 Server I have faced many problems with DNS as IPv6 records where inserted in DNS zone. I have disabled IPv6 from Network properties but it didn’t helped.
