Let’s investigate one more complicated DNS recourse record, the DNS SRV record. It is a very important one that points not only to the service, its location but also the exact port that it uses for communication. Let’s see the DNS SRV record in detail.
What is the DNS SRV record?
The DNS SRV record (service record) is a DNS record that is used to show the service’s port and hostname. What makes it different from other DNS records is that it specifies port too, and not the only hostname. That way, you can set through which port you want to be used a specified service.
