Auto-configuring IPv6 transition mechanisms on customer devices

Are there any (draft, standard, or otherwise) defined mechanisms for indicating to customer-provided devices that they should configure IPv6 to IPv4 transition mechanisms such as MAP, 4rd, 464XLAT, etc. and providing the configuration details thereof? I'm not aware of any. It seems like this

Tier 1s are just as succeptible to outages and peering issues as anyone else. Not to say they're any less, I work for one after all, but one shouldn't assume they're always the best for every application. As an example, Hurricane is decidedly not a Tier 1, but have one of the best peered networks

Hi Graham, Maybe your ASN is not a virgin ASN, someone used it. You should notify every object's former owner or the current maintainer to remove it, or contact RADb or ARIN to help you remove them. But I think that RADb was easier to use than ARIN before, the current version of RADb is not
