Having an issue in our environment.

We have not deployed IPv6 however all windows machines automatically generate an IPv6 6to4 and ISATAP tunnel adapter addresses.These addresses are sometimes registered in DNS and when doing name resolutions for applications, they are returned and connectivity fails.

Is there a way to prevent these addresses from registering or making it to where the tunnel addresses can actually be used for connectivity between hosts internally without deploying full IPv6 solution?
