If you want to add A records in bulk, you must first edit the A records you want to add as a “.csv” file.
Then it will be enough to run the following powershell line.
Import-Csv .\dns.csv | ForEach-Object { Add-DnsServerResourceRecordA -Name $_.Name -IPv4Address $_.IPv4Address -ZoneName yusufustundag.com -ComputerName PDC -CreatePtr}
If you want to check the A records run the following powershell line.
Get-DnsServerResourceRecord -ZoneName yusufustundag.com -RRType A
Have a nice day!
