ctDhcpIfDomainNameServer
Module: CTRON-DHCP-MIB
OID (symbolic): CTRON-DHCP-MIB::ctDhcpIfDomainNameServer
OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.13
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: This value is an DHCP option that can be passed to a client by this interface if it is requested as part of the DHCP process. This value is the IP address of the domain name server to be used by the client.
What is ctDhcpIfDomainNameServer?
ctDhcpIfDomainNameServer is a read-write IP address representing a DHCP option this interface can hand to a requesting client, specifying the domain name server address the client should use. An admin sets this so that clients leasing an address from this interface automatically receive the correct DNS server to use, if they requested that option as part of the DHCP exchange. For example, setting ctDhcpIfDomainNameServer to 10.10.1.5 means clients on that subnet are told to use 10.10.1.5 for name resolution once they accept a lease.
