Google Dynamic DNS Wildcard Subdomains

Question

I can't get Google's Dynamic DNS API to work for a wildcard domain.

I can get defined subdomains to update their IP just fine but I always get nohost when i attempt to update the wildcard's IP.

This page https://support.google.com/domains/answer/6147083?hl=en doesn't mention wildcard domains.

Please let me know how I can improve this question. Thanks! – iambriansreed Feb 20 '15 at 14:38 — iambriansreed, Feb 20 '15 at 14:38

The trick is to create a Synthetic Record for a any subdomain other that *.

Create the synthetic record for wildcard.domainname.com instead of *.domainname.com.

Then create a CNAME record (not synthetic) of the subdomain *.domain.com and point it to your synthetic records subdomain wildcard.domainname.com.

enter image description here

The placeholder subdomain wildcard could really be anything.

This also works to add a static ipv6 AAAA Record to wildcard.example.com, for example if you use tunnelbroker.net – Jacob Evans Jun 07 '16 at 04:04

You can also setup the Dynamic DNS record for `@`, and then make the CNAME record from `*` to `@` to avoid any 'middleman' subdomains. – Greyson Parrelli Jan 20 '21 at 16:15
works in April 2021 with @GreysonParrelli suggestion :-) – patzm Mar 31 '21 at 12:28

You can leave the Google Dynamic DNS "Host name" field blank (empty), click save and it will function like a wildcard (*) for the Google Domain your configuring.
