ISC DHCP Client FQDN Option Configuration
The client FQDN option is sent by the client to indicate its desire to update DNS with its A record or to have the DHCP server perform the update. As such the DHCP server does not provide a configurable option value. However parameters are provided for tracking and processing within the server as follows:
- fqdn.no-client-update flag - when flag = true as set by the client the client will not attempt to update the A record; when flag = true as set by the server the client should not update its A record.
- fqdn.server-update flag - when flag = true as set by the client the client is requesting the server to update its A record; when flag = true as set by the server the server has or will update its A record.
- fqdn.encoded flag - when flag = true the domain name is encoded in DNS wire format and when flag = false the domain name is in ASCII text format.
- fqdn.rcode1 integer - indicates the result code from the DNS server for the A record update
- fqdn.rcode2 integer - indicates the result code from the DNS server for the PTR record update
- fqdn.fqdn text - specifies the fully qualified domain name (or just the hostname) desired by the client
- fqdn.hostname - provides access to the hostname portion of the FQDN for processing
- fqdn.domainname - provides access to the domain name (not including the hostname) for processing
