This could be implemented at the IP view Level in IPAM, and at the IPAM subnet level.
Basically similar to the Poll Now button in NPM, just clicking on the scan button scans the currently view IP for current status, including DHCP/DNS. In the IPAM subnet view, only the selected IP addresses are scanned.
Could be helpful to check if an IP Address or DNS record issue has been resolved. Also possibly give faster feedback that an IP address is in use, or to change the status quickly when assigning IP addresses.
