 ## Service tags 
-A service tag is a group of IP address prefixes that can be assigned to in-bound and out-bound NSG rules. It handles updates to the group of IP address prefixes  without any intervention. This benefits you because you can use service tags to explicitly allow in-bound traffic from Chaos Studio, without needing to know the IP addresses of the platform. Currently service tags can be enabled via PowerShell.
-* Limitation of service tags is that they can only be used with resources that have a public IP address. If a resource only has a private IP address, then service tags will not be able to allow traffic to route to it.
