Description: DNS Server is Dhcp option 6. Default = '' = Null String. The format of the string can be up to 8 IP addresses, for exapmle: '121.23.1.12 135.64.13.190 192.123.242.230' There is no ability to configure this option in the general option table.
What is cigDhcpServersPoolDnsServer?
This object carries the DHCP option 6 (DNS server list) that the pool sends to clients, encoded as a string of up to eight space-separated IP addresses and defaulting to an empty string. Since it lives outside the general option table, this is the only place to set DNS servers for this specific pool, and leaving it blank means clients get no DNS server from DHCP at all. A typical setting like '10.0.0.53 10.0.1.53' would give leased clients a primary and secondary resolver to fall back on if the first is unreachable.
