Docker Registry public IP addresses

hub
dockerhub

(Numanoids) #1

Hi

My firm is going to be standing up some containers and we are using docker hub to build the images. Our target systems are going to be in a DMZ without internet access however we can request certain IP addresses be whitelisted so we can retrieve the images.

The question is what IP addresses does the public docker hub use so that we can request firewall rules be added. Doing a dig on docker.io returns the following IPs but I suspect there may be more that actually represent the registry

52.73.94.64
52.72.231.247
52.4.72.58

Thanks

Hello,

There isn’t a published list of IPs that the official registry uses. They aren’t guaranteed to stay the same and aren’t guaranteed, unfortunately.

Thanks Jeff

I’ll look at mirroring internally.
