Windows dhcp not updating dns
Dynamic DNS (DDNS) is a method of automatically updating a name server in the Domain Name Server (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.
The term is used to describe two different concepts.
Dynamic IP addresses present a problem if the customer wants to provide a service to other users on the Internet, such as a web service.
As the IP address may change frequently, corresponding domain names must be quickly re-mapped in the DNS, to maintain accessibility using a well-known URL.
The second kind of dynamic DNS permits lightweight and immediate updates often using an update client, which do not use the RFC2136 standard for updating DNS records.
These clients provide a persistent addressing method for devices that change their location, configuration or IP address frequently.
Dynamic DNS is a system that addresses the problem of rapid updates.
The term is used in two ways, which, while technically similar, have very different purposes and user populations.
The automatic reconfiguration is generally implemented in the user's router or computer, which runs software to update the DDNS service.DHCP became an important tool for ISPs as well to manage their address spaces for connecting home and small-business end-users with a single IP address each by implementing network address translation (NAT) at the customer-premises router.The private network behind these routers uses address space set aside for these purposes (RFC 1918), masqueraded by the NAT device.Smaller services, however, are generally much more likely to move from host to host over shorter periods of time.Servers being run on certain types of Internet service provider, cable modems in particular, are likely to change their IP address over very short periods of time, on the order of days or hours.
