Phil Thanks for your comments my big fair is our Micros POS system. I also need to do some research if it is best to get an IPv6 allocation from ICANN or if it is best to use IPv6 ULA prefix for are internal network. Cheers Ryan

There are several exceptions, one being dual-stacked hosts - machines with both IPv4 and IPv6 connectivity. Unless you're going to set up a new Exchange server specifically for this MPLS network - an Exchange server that won't be able to talk to anyone else - you're going to need to start implementing IPv6 company-wide. Perform due diligence! Microsoft's products most likely won't be an issue, especially if you're using the latest & greatest. I can't say the same for niche products, like your point-of-sale software and/or hardware... In the highly likely event you don't have an IPv6 allocation from your ISP, ICANN, ARIN, APNIC, RIPE - or whoever the appropriate body would be for your organization - you should make sure you're using a ULA prefix (Unique Local Address: http://en.wikipedia.org/wiki/Unique_local_address; http://tools.ietf.org/html/rfc4193). In IPv6, the ULA address space is roughly equivalent to the RFC1918 subnets (aka 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). The site-local prefix fec0::/10 was depreciated by RFC3879.
