Is it possible in Infoblox DHCP appliances not to release the IP when requested from host outside the domain? ie, it should not release IP when requested by an unknown host.
in the DHCP IPV4 option filter I can see many optiond for DNS, like
option 6- domain-name servers(6) array of ip address
option 15 - domain name(15)text
option 81 - fqdn(81)string
option 119 - domain search(119)string
and,many more.(screenshot attached
any could give an insight into this?
which option will work for me and the steps to implement it and possible impact on the network
