Do 2 ips lead to the same site?

Question

Nginx

there are 2 ip, 2 domains, 1 server named domain1.com
for one site is specified in the config

...
listen ip1:80;
root /var/www/domain1.com/html;
index index.php;
server_name domain1.com www.domain1.com;
....

for another

...
listen ip2:80;
root /var/www/domain2.com/html;
index index.php;
server_name domain2.com www.domain2.com;
....

But both ip and both domain names lead to domain1.com corresponding to the server name
. What could be the reason?

Answer 1

Show sections with proxy_pass or php-fpm - maybe the reason is there.
So, of course, I would like to see the patients to make sure that everything resolves correctly and complete configs.
