Microsoft Edge: Changes to local IP address detection for proxy auto-config (PAC) scripts Beta
Data as of 42 minutes ago (9 September 2026)
Description
Microsoft Edge is changing how it selects the local network address reported to proxy auto-config (PAC) scripts and is adding administrator control over it. The default IPv4 and IPv6 probe destinations now match Chromium’s defaults. Administrators can override these defaults using the PacMyIpAddressIPv4ProbeAddress and PacMyIpAddressIPv6ProbeAddress policies when required by their network routing.
