Generating NIOS-X Server Names for DDNS Updates
- Sri Raghu
Some IPv4 clients do not send a NIOS-X Server name with their DHCP requests. When the DHCP server receives such a request, its default behavior is to provide a lease but not update DNS. You can configure the DHCP server to generate a NIOS-X Server name and update DNS with this NIOS-X Server name when it receives a DHCP request that does not include a NIOS-X Server name. It generates a name in the following format: dhcp-ip_address, where ip_address is the IP address of the lease. For example, if this feature is enabled and the DHCP server receives a DHCP REQUEST from an IPv4 DHCP client with IP address 10.1.1.1 and no NIOS-X Server name, the DHCP server generates the name dhcp-10-1-1-1 and appends the domain name, if specified, for the DDNS update.
