Webhook IP changed?

According to the documentation the webhooks will always come from ip addresses in the range 162.242.195.64 - 162.242.195.127. I have relied on this to make sure only the docker hub can deploy to my server by checking the ip of incoming requests. But recently this has started to fail, as the remote IP addresses is 52.4.218.96. Is there a new range of ip addresses that the webhooks can come from?

I’m sorry, I’m going to update that doc today.

it seems that we’ve moved this infrastructure to Amazon elastic IP’s, so for now, there is no range we can give you to filter to.

Does this also explain why when i manually map out a port with docker run -p IP:HostPort:ContainerPort it states that i cant bind unless the ip was to the local host?
