Hi!

I was setting up some dynu dyndns when I saw that each host had created A and AAAA entries but also WCA and WCAAAA entries.

I don't know what these are and couldn't find on internet what they stands for.
May you explain me what are WCA and WCAAAA entries for ?

Besides, everything works well and subdomains of subdomains are great ! (for free users) :D

Wildcard alias for A record and wildcard alias for AAAA record.

(Sorry for double message, I though it hadn't been sent, just look at the next one)

Thanks ! I had never heard of it before and couldn't find anything on WCA or WCAAAA.
Still I don't really understand the difference with the 'normal' A and AAAA entries, since I can put *.my.domain.net with a normal A or AAAA.

I red that it is used to answer to nonexistent subDNS domains but what is the difference with *.my.domain.net ?

Does it mean that if I disable it, blog.my.domain.net will return nothing but an error if not precised in the entries (the DNS Zone thing, I think it's called) ?

Thanks for helping !

I couldn't find it by searching WCA or WCAAAA.

Still, I don't clearly understand it's goal.
I though that a A entry like *.my.domain.net was already handling all the non-existing subdomains by redirecting to the my.domain.net IP by default.

Does it mean that if I disable the Wildcard option, subdomains like blog.my.domain.net won't be redirect to the my.domain.net IP address ?

Enabling wildcard alias option creates an A entry *.my.domain.net pointing to the IP of my.domain.net.

You are right about this point.If you disable Wildcard option, subdomain names not defined in the DNS zones will not be pointing to the my.domain.net IP address but will be treated as non-existing.

Thanks for answering.
Indeed, I can confirm that disabling the wildcard option leaded me to errors (domain not found) when I attempted to resolve a not referenced subdomain.

Thanks to you two for helping.
