If you select Determine location by GPS coordinates, the user will need to have the Microsoft Authenticator app installed on their mobile device. Only IPv4 addresses can be mapped to countries or regions. Sign-ins from IPv6 addresses cannot be mapped to countries or regions, and are considered unknown areas. Organizations can use named locations defined by countries to block traffic from countries where they don't do business. When a user signs in, Azure AD resolves the user's IPv4 address to a country or region, and the mapping is updated periodically. If you select Determine location by IP address (IPv4 only), the system will collect the IP address of the device the user is signing into. Optionally choose to Include unknown countries/regions.Choose to determine location by IP address or GPS coordinates.To define a named location by country, you'll need to provide: Organizations can determine country location by IP address or GPS coordinates.

For example, you may restrict multi-factor authentication registration to trusted locations. Additionally, trusted named locations can be targeted in Conditional Access policies. Sign-ins from trusted named locations improve the accuracy of Azure AD Identity Protection's risk calculation, lowering a user's sign-in risk when they authenticate from a location marked as trusted. Only CIDR masks greater than /8 are allowed when defining an IP range.Īdministrators can name locations defined by IP address ranges to be trusted named locations. The number of IP addresses contained in a range is limited.Both IPv4 and IPv6 ranges are supported.Configure up to 2000 IP ranges per named location.Named locations defined by IPv4/IPv6 address ranges are subject to the following limitations: To define a named location by IPv4/IPv6 address ranges, you'll need to provide: Named locations can be defined by IPv4/IPv6 address ranges or by countries. These named network locations may include locations like an organization's headquarters network ranges, VPN network ranges, or ranges that you wish to block.

Locations are named in the Azure portal under Azure Active Directory > Security > Conditional Access > Named locations. Conditional Access policies by default apply to all IPv4 and IPv6 addresses. The location is determined by the public IP address a client provides to Azure Active Directory or GPS coordinates provided by the Microsoft Authenticator app.
