Linux dhcp client not updating dns
Have you ticked the dox in DNS properties on the server role that is listed as "Dynamically update DNS A and PTR records for DHCP client that do not request updated (for example, clients running Windows NT 4.0)?DDNS is handy if you have a DNS Server in your local network that should be able to resolve the names of your local PCs.By default the DHCP-Server doesn't update the DNS entries of static leases.If you want it to update them, you need to set this option to on.``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.The primary statement specifies the IP address of the name server whose zone information is to be updated.In this case DHCP and DNS server are running on the same machine, that's why we put 127.0.0.1 there.
I have an Ubuntu 14.04 server which is getting addresses via DHCP. In the Windows DHCP server, I have converted the lease to a reservation.
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.
