Hi, Can you try to re-create the same vnet. Delete the DDOS plan and afterwards delete the vnet again?

Otherwise you will need to raise support ticket.

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you would like to know about what happens to DDOS Protection when a VNET is deleted.

May I ask how are you saying the deleted VNET is still covered under the DDOS Plan?

Do you see the VNET under View protected resources of the DDOS plan?

If so, can you please share a screenshot of the deleted VNET listing under the DDOS Plan?

Cheers,

Kapil

Hey KapilAnanth-MSFT,

I think what the OP is saying is that:

op created a vnet

op created a DDoS Network Plan

op associated the DDoS Plan to the vnet

op deleted the vnet

After doing all of that, op can't delete the DDoS plan because the plan thinks it is still associated with the deleted vnet.

I have the same issue, how can I solve it?

Thank you,

The way to solve this problem is to:

Create a new vnet with the same name as the one deleted before DDoS Plan was removed from it

Associate the vnet with the DDoS plan

Delete the vnet from the list of DDoS plan protected resources

Finally, delete your DDoS plan

Hope this helps!

Hi @Pravin Bobade
Is this disassociation due to billing? If yes, just remove the DDoS protection plan, you can do this by deleting the plan as with the command below:

az network ddos-protection delete --name YourDdosPlanName --resource-group YourResourceGroupName

Now if you just want to make sure that there is no association in the Vnet you can use the command below

az network vnet update --name YourVNetName --resource-group YourResourceGroupName --remove ddosProtectionPlan

In my case there is nothing left after I deleted the vnet.
I did it in my laboratory and I had no problems with having something associated ###DDoS Enable ####

DDoS Plan

Protected Resource
