| Round robin is actually a simple concept. Let's say you have 3 IP address for the same host name. This is a load balancing technique. For example you have
192.168.59.1
192.168.59.2
192.168.59.3
When a resolver requests an IP for that FQDN, the DNS server will give a list of IPs
hostnameIN A 192.168.59.1
hostnameIN A 192.168.59.2
hostnameIN A 192.168.59.3
When another client requests another resolution for the same FQDN, the DNS server will rotate through the list until they are all used. For example the second request would yield the following:
hostnameIN A 192.168.59.2
hostnameIN A 192.168.59.3
hostnameIN A 192.168.59.1
I know these aren't questions like you asked for. But if you understand what it is then you shouldn't have a problem with the questions as it is a really simple concept. | |
