Do DHCP servers use DNS?
The DHCP service can use DNS in two ways: The DHCP server can look up the host name that is mapped to an IP address that the server is assigning to the client. The DHCP server can attempt to make a DNS mapping on a client’s behalf, if the DHCP server is configured to update DNS.
What is the difference between DNS and DHCP server?
While DNS maps the name of the domain to the IP address, DHCP is a protocol that assigns the IP address to the host in a network either dynamically or statically….DNS vs. DHCP.
| DNS | DHCP | |
|---|---|---|
| Purpose | You can use DNS for locating or finding the Active Directory domain servers | DHCP can provide IP to host for some limited time |
Is there a role for DHCP in DNS server?
There is no role of DHCP here. Please note that as the zone accepts only secure update, Server1 must be a member of AD Domain so that it can register/update the record in DNS server. Now, let’s assume we have a workstation named WS1. The IP address is assigned by DHCP Server A, so the DNS record will be registered and owned by DHCP server A.
How to force DHCP to update Domain Name System?
If you insist on doing this from the server end of things, it should be possible to write a custom program to read the entries from a DHCP lease export, and register the addresses, but be sure to run it as the same account that DHCP uses for registrations, or else it may have trouble updating the entries in the future.
Can a DHCP server update a DNS record?
The IP address is assigned by DHCP Server A, so the DNS record will be registered and owned by DHCP server A. No other system, including WS1 or any other DHCP server, can update this record. There is a major drawback in the approach, where a single DHCP server is becoming an owner of a huge number of records.
How to force Windows 10 to use our custom DNS server?
On windows 7 and 8, we used a custom DNS Server listening on port 53 on the laptop generating the wifi and everything worked very well. Computers on our network used automatically our DNS (except the one which emits the wifi and that is cool). On windows 10, computers on the network don’t use any DNS Server.
