What are the domain's extended attributes?


Quick Answer

Certain country-code TLDs such as.CA,.COM.AU,.COM.ES,.ES,.FR,.NOM.ES,.NET.AU,.NU,.ORG.AU,.ORG.ES,.SG,.UK,.US, generic TLDs like .XXX and.NYC require that you provide some additional information while registering domains. This mandatory additional information is called extended attributes. These attributes can be specified explicitly during the checkout (you need to use standard Checkout instead of Express Checkout).

  • Identify the exact domain or product affected.

Troubleshooting

  • The change was made in the wrong account or on the wrong product.
  • The panel saved the request but the downstream registry or service is still processing it.
  • A dependent DNS, email, browser cache or security setting still uses the old value.
  • The support ticket does not include the affected item, error message and time of failure.
