My dns is not updating

The following steps only illustrate how to turn off dynamic DNS updates on Microsoft Windows™ systems.

For Linux or Free BSD systems that use ISC's DHCP client and server software, the dynamic DNS update feature gets set to off by default and requires manual intervention to turn on the service.

These name servers tell DNS where to get information about how you want traffic for your domain to be routed, for example, to the IP address of a web server for your domain.

Both DHCP clients and servers can generate DNS updates.

To turn off DNS updates on Windows 2000/XP/2003 configured with DHCP clients (refer to Figure 1): To turn off DNS updates on Window Server 2000 running DHCP Server (refer to Figure 2 below): Microsoft Windows Server 2003™ automatically sends DNS updates to each of its DHCP clients.

If you changed the settings in a record but your traffic is still being routed to the old resource, such as a web server for your website, one possible cause is that DNS still has the previous settings cached.

Each record has a TTL (time to live) value that specifies how long, in seconds, that you want DNS resolvers to cache the information in the record, such as the IP address for a web server.

Only if you know with certainty that the updates get sent only to a local DNS server should you run the Dynamic DNS Updates service.

Most home users who use DSL/Cable routers as DHCP/NAT servers to facilitate multiple host connections to the Internet should turn off dynamic DNS updates.

To determine whether the registrar is using the name servers for your Route 53 hosted zone and, if necessary, to update the name servers for the domain, perform the following procedure: To get the name servers for your hosted zone and update the name server setting with the domain registrar Important When you change the name servers for the domain to the name servers from your Route 53 hosted zone, it can take up to two days for the change to take effect and for Route 53 to become your DNS service.

This is because DNS resolvers across the internet typically request the name servers only once every two days and cache the answer.

Microsoft Windows operating systems support a feature that dynamically updates the mappings of domain names to associated IP addresses assigned to hosts by DHCP servers.

This automatic updating, called Dynamic DNS Updates service, reduces the administrative overhead associated with manually administering DNS records of network hosts.

While this service can reduce administrative overhead, it also can, and does, have deleterious effects on the larger Internet by leaking traffic regarding private IP addresses that should never leave the local area network.
