Using wildcard does not resolve sub of subdomain
I have a domain xyz.com
on (xx.xxx.255.25) and sub.xyz.com
on (xx.xxx.255.240)
To resolve sub
I added the following reocrd in BIND
sub IN A xx.xxx.255.240
*.sub IN A xx.xxx.255.240
and worked well, but the problem is with the sub of subdomain it did not resolve.
I tried adding a test
sub and worked well:
test.sub IN A xx.xxx.255.240
The point of the wildcard (*) is that I have multiple subs (FTP, mail, SMTP...
)
So where exactly I did wrong caused the sub of the subdomain to not resolve?
[UPDATE]
Resolving sub of subdomains worked as *@Tommiie* said, but the second problem appeared is with `TXT` records (SPF, DKIM, DMARC), Can I add wildacrd as `A records` to resolve them?Solution 1:
Do you have other records in the sub
subdomain?
The wildcard character matches any number of labels in a name as long as there isn't an exact match with a name already in the name server's database.
Quote from DNS & BIND (5th edition), p. 488
As you also want TXT wildcard records:
*.sub.example.com. A xx.xxx.255.240
*.sub.example.com. TXT "spv record"
*.sub.example.com. TXT "dkim record"
*.sub.example.com. TXT "more text records"
Please share a more complete configuration.
PS: remove the trailing dots. It wont work with them in place.
