Hello,
Can we lookup hostname if we know the ip address but looking in forward lookup zones?
I try use command ping -a 10.10.10.10, Resolve-DnsName -Name 10.10.10.10, [System.Net.Dns]::GetHostEntry(10.10.10.10).HostName but all commands will looking on reverse lookup zone.
The problem is not all ip have the reverse domain.

Forward lookup zones are designed to map domain names to IP addresses, not the other way around. To find a hostname from an IP address, you need to use a reverse lookup zone, which maps IP addresses to hostnames.
Since not all IPs have reverse DNS records, you might not always get a hostname for every IP address. If you need to manage costs and track usage by project/application, you might consider implementing a custom solution to log and analyze IP addresses and their associated activities.
