I have tens of sites listening on multiple ip addresses at nginx. For example, 

server {listen 172.16.33.1:80; server_name a.com}
..
server {listen 172.16.33.1:80; server_name f.com}
server {listen 172.16.33.2:80; server_name d.com}
..
server {listen 172.16.33.2:80; server_name r.com}
server {listen 172.16.33.1:443; server_name aa.com}
server {listen 172.16.33.2:443; server_name bb.com}
server {listen 172.16.33.3:443; server_name cc.com}

Is there any possible way to set listen ips to variables? Like "$ip1=172.16.33.1; $ip2=172.16.33.2;" and then change conf to 

server {listen $ip1:443; server_name aa.com}
server {listen $ip2:443; server_name bb.com}

I know about search and replace in every text editor, but it would be more easy when you change listen ip once to make effect on all corresponding sites.

Nginx by default don't support variables for the listen directive.

But another approach to dynamically configure Nginx is by using ansible

Here you can check the roles: https://galaxy.ansible.com/nginxinc/

And here you can read more about ansible: https://www.ansible.com/
