Dynamic DNS(DDNS)

Map static domain name to dynamic IP address. Most of the internet providers does not provide us with static IP address, and instead, they probably use PPPoE with DHCP. Thus, we get dynamic but unique IP address. In order to connect to our own servers, we can use DDNS service provider to bind our dynamic IP address to a static DNS URL.

Here are some DDNS service providers:

• oray.com
• 3322.org
• dyndns.com
• no-ip.com

• According to wikipedia, a DMZ or demilitarized zone (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually the Internet. It can map a subnet device to a gateway wireless router and act as a public network interface.
