[16:05:19] <ChriChri[m]> I have a question about DNS:
The diagnosis says that I'm missing records like `A * IP` for domains. I set records for each `CNAME subdomain do.main.` and everything is working. On those domains there are some other subdomains that point to other IPs, too. Is there any reason yunohost insists that there is some wildcard record?
[16:56:16] <Aleks (he/him/il/lui)> hmpf there are some pro and cons for defining the wildcard
[16:56:50] <Aleks (he/him/il/lui)> pros: when you want to create subdomains, it's a pain in the ass to have to copy paste the same A record for every new subdomain. Defining the wildcard allows to stop caring about it
[16:57:40] <Aleks (he/him/il/lui)> cons: it makes it "as if" every typoed domain like "whatever.yourdomain.tld" exists, and this will be caught by nginx which will present a certificate that is not valid for that domain
[18:56:45] <ChriChri[m]> > <@Alekswag:matrix.org> hmpf there are some pro and cons for defining the wildcard

Maybe it would be worth to change the test to really check on the needed resolutions and not care about how they are achived?
[19:59:10] <Aleks (he/him/il/lui)> i can't see exactly what you are talking about if you don't share the exact diagnosis message you are reffering to
