Indicates the minimum number of seconds the DHCP server keeps the
DNS records acquired through dynamic updates. This value sets the
shortest allowable time (or time to live) to keep DNS updates.
When the DHCP server adds a DNS record, it uses a TTL of one
third the lease time if it is between min-dns-ttl and
max-dns-ttl values. If one third of the lease time is smaller
than min-dns-ttl, the TTL value will be set to min-dns-ttl.
name string required,unique,immutable
Gives a unique name to the configuration object.
reverse-zone-name dname
Designates the DNS reverse (in-addr.arpa) zone that is updated
with PTR records.
If a reverse-zone-name is configured, DHCP always uses it.
Alternately, if DHCP server synthesize-reverse-zone feature is
enabled and if a reverse-zone-name is not configured, DHCP
uses the lease IP address and the scope dns-host-bytes to
automatically generate a reverse zone name.
reverse-zone-prefix-length rangeint(0-124)
Identifies the prefix length of the reverse zone for ip6.arpa
updates. The server forms the zone name using this value if
configured; otherwise the prefix length is determined from the
Prefix. This value must be a multiple of 4 as ip6.arpa zones are
on 4 bit (nibble) boundaries. If not a multiple of 4, it is
rounded up to the next higher multiple of 4.
server-addr ipaddr
Specifies the DNS server address that receives dynamic DNS updates.
server-key nameref(Key)
Specifies the TSIG key used to process all dynamic DNS updates for
server-addr.
synthesize-name bool default = disabled
Controls whether the DHCP server automatically creates DNS host
names for DHCP clients that do not provide names. The server
can synthesize unique names for clients based on the 'synthetic
name stem' attribute.
synthetic-name-stem string default = dhcp
Identifies the stem of the default host name to use if clients do not
supply host names.
update-dns-first bool default = disabled
Controls whether to update the DNS server before granting a lease.
update-dns-for-bootp bool default = enabled
