How to configure ip matching in zabbix?

Question

Zabbix

I just started to learn monitoring.
how to check the ip of sites (about 300) so that ip matches one of the list
as an example ya.ru, yandex.ru - if ip is 123.123.123.123 or 234.234.234.234 then everything is in order, otherwise it sends a message to email.
need at least a manual-example. thanks in advance.

There is no way to do it natively and beautifully, if your fools have access to the dns manager, just close it.
