IPv6 Auto-Config EUI-64 converter

IF you need to know the auto-configured address for a NIC before enabling IPv6 in a network the following webpage can help you; http://73837.net/

Simply put in your advertised /64 prefix (or any IPv6 address - it will only take the first 64 bits) and the host MAC address, and you'll get the auto-configured address. This was built according to the RFC3513 and correctly inverts the seventh bit of the EUI-64 address. The eighth bit, for group/host indication, is not modified.
