+Subject: [PATCH 1/2] Fix GHSA-w8qr-v226-r27w
+
+We should not early-out with success status if we found an ipv6
+hostname, we should keep checking the rest of the conditions.
+Because integrating the if-check of the ipv6 hostname in the
+"Validate domain" if-check made the code hard to read, I extracted the
+condition out to a separate function. This also required to make
+a few pointers const in order to have some clean code.
+
