One Mac showing two IPs
Why is ARD showing two IPs for just one of my Macs?
Ido not have multiple IPs setup
Thanks for your help {-)

The long address is an IPv6 one. If you're not aware of the differences the following explains them quite well:
Your mac is primed to receive an IPv6 from whatever routing/network/firewall device you connect to. If you have control over your firewall (BT Home Hub for example) you can disable the option. BT Home Hubs dole out IPv6 addresses by default and maybe your DHCP server does the same?
You can't disable IPv6 using the GUI on a Mac. You have to use a terminal command instead. Depending on your hardware and which network port you want to disable it on, this can be any or all of the following:
networksetup -setv6off Wi-Fi
networksetup -setV6off Ethernet
networksetup -setv6off "Thunderbolt Ethernet"
You will need to precede the above with sudo or, depending on your OS version, you'll be prompted for an admin name and password. You can send the above to target workstations using ARD's Send Terminal Command option. Make sure you send the command as root. Once sent it's a good idea to reboot the macs in question as well as removing the entry for those macs in ARD and re-adding them.
Hopefully this may help?
