The earliest recollection of this bug is traced back to PAN-OS 10.1.11 - May 06, 2026. This bug is fixed in PAN-OS versions 10.1.11-h5. Fixed an issue where DNS resolution failed on platforms that obtained DNS server IP addresses from DHCP. DNS resolution may fail if DNS server IP is obtained through DHCP. Workaround: Configure the DNS server with a static IP or renew the DHCP IP when you see the issue. This issue affects PAN-OS 10.1.11-h4 only.
