This way, the domain is always updated no matter how many times its IP address changes. As the ISP changes the IP address it assigned to the Cisco router, the router in turn will also update its DDNS provider. When an Internet host queries the DDNS provider for the domain, it will then point the host towards the public IP addresses currently assigned to the router, that is, 195.162.29.1. Once received, the DDNS provider updates the relevant DNS records, in our example,. It shows the simple logic of how DDNS works:ДЇirstly we need to configure our Cisco router to register and send its periodical updates to the DDNS provider.

DDNS providers allow the registeration and creation of Fully Qualified Domain Names (FQDN) that can be mapped to home or branch office Internet connections without cost. The solution to the above problem is named 'DDNS' - Dynamic DNS Service. While this is the recommended setup for most companies doing serious business, it doesn't really apply to home users or small branch offices because of the increased cost for static IP addresses. If you had a domain name, e.g Firewall.cx, you would then map your static IP address to your domain (via DNS) so when you hit your domain name, you would be directed to your statically assigned IP address and access the resources you need.

This ensures that your services are always reachable using the same IP address or domain name. Note: IPv6 support in OpenDNS is limited to standard recursive DNS.Hosting your own webserver or email server would normaly require a static IP address from your ISP.

IPv6 supports a far larger number of addresses than IPv4, which is why the change is taking place now - since IPv4 was implemented in 1981, the Internet has grown dramatically, and there are no more available IPv4 addresses. OpenDNS now supports IPv6 addresses - meaning that, by using the OpenDNS Sandbox, youвЂ™ll be able to resolve your DNS using IPv6 DNS servers. The last block of IPv4 addresses have been allocated, and itвЂ™s time to get your network ready. IPv6 Looking for IPv6 information for Cisco Umbrella? Visit: /ipv6 Get Your Network Ready for IPv6
