    169169=== DDNS ===
    170 DDNS (stored in configuration, optional copies stored in DB): the following information about DNS Update MUST be stored. This information must be kept even after defined configuration has changed; it is required when attempting to clean up old leases. Records can be safely removed when there are no leases pointing to it. DDNS data (dns-server-address, secret-key, algorithm) are stored in a configuration.
    171 1. ddns-id or name - a primary key (unique value that allows referencing specific entry in this table)
    172 2. dns-server-address - specifies DNS server address
    173 3. secret-key - specifies secret key used for DNS Update signatures
    174 4. algorithm - initially only TSIG with MD5 will be supported)
     170The DDNS component of the system is the subject of a separate set of [wiki:DhcpDdnsRequirements requirements] and [wiki:DhcpDdnsDesign design].
     171
     172In brief, information about a DDNS update is stored in the system and is associated with the relevant lease.  It is retained for the duration of the lease, this being the case even after a configuration change; it is required when attempting to clean up old leases. DNS records can be safely removed when there are no leases associated with it.
