IPv6 Support
IPv6 (IP version 6) is slowly gaining popularity, mostly out of necessity. The fact is, if we
don??™t convert to IPv6 in the near future, we will simply run out of usable IP addresses.
IPv6 uses 128 bits to specify IP addresses versus the traditional 32 bits used by IPv4. The
catch is that in order to take advantage of IPV6, you will need to have IPv6-capable networking
equipment as well as operating systems that are IPv6 capable, such as Windows
Server 2008 on the server side and Windows Vista on the desktop side.
Since the change in addressing will affect every piece of infrastructure that deals
with TCP/IP, Microsoft has included IPv6 support into Windows Server 2008 DNS. This
allows DNS entries to be specified either as IPv4 or IPv6 addresses. In addition to this,
command-line tools for managing DNS, such as DNSCMD.EXE, also support using IPv6
as parameters. This support doesn??™t stop with host entries, as it can also forward to
or perform recursive queries on IPv6 servers. DNS also supports the ip6.arpa domain
namespace for reverse name resolution of IPv6 addresses.
IMPORTANT Microsoft strongly recommends that your DNS clients are upgraded to support IPv6
as well. This is because name resolution against a Windows Server 2008 DNS server can result in
either an IPv4 (A) record or an IPv6 (AAAA) record.
