What's the Difference in a Static and Dynamic NAT?
NAT or Network Address Translation is a networking mapping protocol where public IP addresses are assigned to private network-connected devices and or computers on the network protected behind a firewall on a private network. In facilitating this process, network admins often utilize either a Static NAT protocol or a Dynamic NAT protocol to properly address devices within a private network.
Static NAT is a NAT protocol used to provide a one-to-one mapping between outside public IP addresses and internal devices within a private network. Often the static NAT protocol is uses to ensure a single one-to-one connection between servers in multiple locations such as a web server that you would like accessible to the outside world, via one static IP address.
Dynamic NAT is a NAT protocol that dynamically assigns internal devices an IP address taken from a "pool" of available IP addresses. This process allows devices to be assigned an IP dynamically. This NAT protocol can be very effective by immediately applying new dynamic IP addresses to devices as they come on the network, avoiding the need to statically assign IPs to these devices.
