Dhcp address not updating in dns

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

``So what if my host leaks a few packets to the global Internet? '' The reason is that inconsistent configuration between your home hosts and your local DNS servers can, and often does, cause leakage of DNS updates for private IP addresses to the global Internet.

This leakage causes the following problems: Unfortunately, most users have no knowledge of their own misbehaving hosts broadcasting private information to the world.

You, as a DHCP administrator, might want to enable DNS integration in order to automatically update the DNS records dynamically with the DHCP client computers’ information whenever the DHCP server assigns the IP address and other settings to them.

Since the DHCP server always assigns the dynamic IP addresses to the client computers which may change from time to time, and the DNS maintains the records of the information about the host names and their corresponding IP addresses, there must be some technology with the help of which the DNS server records can automatically get updated with the latest IP addresses that the DHCP server has assigned to the DHCP clients.

By commenting, you are accepting the DISQUS terms of service.
