    Hello @kimjaeho

    You can change Azure VM IP address from Azure Portal

    1. Create new Public IP resource in Azure Portal
    2. Select VM resource in Azure Portal
    3. Select Networking in Settings in your VM resource.
    4. In Networking, select the Network interface of the VM. The name of the NIC will be prefixed with the name of the VM and end with a random number.

    5. In Settings of the network interface, select IP configurations.
    6. Select ipconfig1 in IP configurations.

    You can create Azure Automation Account and add below script to create new Public IP and associate it with the VM:
    Example: 

    $ip = @{  
    Name = '<PublicIPName>'  
    ResourceGroupName = '<ResourceGroupName>'  
    Location = '<Location>'  
    Sku = 'Standard'  
    AllocationMethod = 'Static'  
    IpAddressVersion = 'IPv4'  
    Zone = 1,2,3  
}  
$newPublicIp = New-AzPublicIpAddress @ip  
  
$vnet = Get-AzVirtualNetwork -Name <VirtualNetworkName> -ResourceGroupName <ResourceGroupName>  
$subnet = Get-AzVirtualNetworkSubnetConfig -Name <VMSubnetName> -VirtualNetwork $vnet  
$nic = Get-AzNetworkInterface -<VMNicName> -ResourceGroupName <ResourceGroupName>  
$nic | Set-AzNetworkInterfaceIpConfig -Name ipconfigName -PublicIPAddress $newPublicIp -Subnet $subnet  
$nic | Set-AzNetworkInterface

    Yes, you can use your custom script to change the PIP on a weekly basis. For PowerShell use these set commands in your automation,

    Set-AzNetworkInterfaceIpConfig
