Get Public IP Address ResourceId from IP Address

[rajdhandus]

Is there a way to get the Azure Resource ID of a given Public IP if we know the IP address?

Input:- 40.81.207.37
Output:- /subscription/xxxx/resourceGroups/xxxx/providers/Microsoft.Network/publicIPAddresses/

Azure.ResourceManager.Network.PublicIPAddressCollection doesn't seem to have the necessary method..

Hi @rajdhandus , thank you for your feedback. If you only have the IpAddress, there is no such method in the SDK to obtain the corresponding ResourceID. However, if you know the subscription and resourceName you are using, you can try the following method to obtain the ID:
var sub = await ArmClient.GetSubscriptionResourceAsync(subId);
var rg = await subscription.GetResourceGroupAsync(resourceGroupName);
var publicIPAddressCollection = rg.GetPublicIPAddresses();
string yourIPAddress = "";
AsyncPageable<PublicIPAddressResource> getPublicIpAddressListResponseAP = publicIPAddressCollection.GetAllAsync();
List<PublicIPAddressResource> getPublicIpAddressListResponse = await getPublicIpAddressListResponseAP.ToEnumerableAsync();
foreach (PublicIPAddressResource resource in getPublicIpAddressListResponse)
{
if (resource.Data.IPAddress != null)
{
if (resource.Data.IPAddress == yourIPAddress)
{
Console.WriteLine($"Azure Resource ID of the public IP address {yourIPAddress} is {resource.Id}");
}
}
else
{
Console.WriteLine($"Public IP address {yourIPAddress} not found in your subscription.");
}
}
Output: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/publicIPAddresses/{publicIpAddressName}
