If you work with Azure Active Directory (AAD, Azure AD), you should already know the Named Locations (also known as Trusted Locations) settings which allows you to define a list of IP addresses or ranges to be marked as trusted or not and then can be used with Conditional Access.
Well, the administration experience for the Named Location has a new interface in preview, which I think make it easier to manage.
The next time you logon to your Azure (https://portal.azure.com) or Azure AD (https://aad.portal.azure.com) portal to manage the Named Locations you will see a banner telling you a new experience is available and it will replace the current one soon
NOTE please note that any changes done using the new/preview experience will not be visible with the current one but will be still applied
The Named Locations blade can be accessed from Azure Active Directory\Security\Named Locations
Below the ‘old/current’ experience and the new one to compare
