Newbie webmaster here: I have 2 domains
mydomain.net. I want a permanent redirect so that if anyone browses to
mydomain.net they navigate to
mydomain.com. Is there a way to do this using DNS records?
You won't be able to "redirect" using DNS records.
You could create a CNAME record for your
.netdomain, this way your DNS will translate
This is a good first step, but this only sets the domain to point to the same IP, it doesn't actually perform any redirecting. Once the domain is pointing to the same place you can then set your webserver (Apache/NGINX/IIS/&c) to HTTP redirect traffic from one domain to the other.
You can try http://redirect.center.
In your case, configure your DNS like this:
mydomain.net A 18.104.22.168 redirect.mydomain.net CNAME www.mydomain.com.redirect.center www.mydomain.net CNAME www.mydomain.redirect.center
