htaccess: Allow from domain name instead of IP/subnet

Question

On my Authentication page i have it only allow from certain IPs. Is it possible to have it allow by a domain name? The IP of my home network is dynamic but the domain name (mysite.com) always points to the correct IP address.

Answer 1

I came across this because I had the same problem.

Just in case anyone else finds this, I found the perfect solution:

Beginning in Apache 2.4.19, you can use the parameter "Require forward-dns [hostname]", which simply allows all IPs behind [hostname].
