Close access by IP nginx?

Question

Nginx

There was a need to make the site inaccessible from an external IP ( http://12.34.56.78).
That is, available only to the domain name.
What is the best way to implement this?

Answer 1

server {
listen 80 default_server;
server_name_;
return 444;
}
instead of 444, you can use some kind of "bandwich limit"
PS options with listing domains (like colleagues in the answers) will backfire when adding subdomains and not only

Answer 2

if ($host !~* ^(domain.tld|www.domain.tld|abc.domain.tld)$ ) {
                return 444;
        }

In the config for your domain, it will send everyone who came for something other than the names indicated in brackets to the frog grandmother. What is the entry by IP, what is the resolution of your IP officer into something else.
I have such a design provided with a config for each domain. Thus, I cut off all unnecessary calls.

Answer 3

Make a redirect from IP to domain, something like this:

server {
        listen 12.34.56.78:80;
        server_name example.com www.example.com;
location / {
        rewrite ^(.*)$ http://example.com$1 break;
        }
}
