Network is a subnet of another members closed network

[roger.l]

Hi, I have an issue where I cannot update nor reinstate (I deleted while trying to fix it) the network on my IP - it gives the error "Network is a subnet of another members closed network". Please help!! I have logged a job with support 2 days ago but had no response of any kind so far.

You did it right with opening a support ticket.  The usual reponse time is 72 hours within workdays, sometimes longer if many tickets are in their queue.

"I deleted while trying to fix it"

This is always the wrong approach.

In hindsight, true... but it seemed like a good idea at the time!
