Mobile Phones not resolving DNS without FQDN

What is the name of the domain?

company.local

What is the issue you’re encountering

I set up Cloudflare Tunnel with a cloudflared Service on a Windows Server here in our buildung. I deployed the WARP Client to our endpoints and phones. Notebooks reolve servername/ perfectly, while the phones need servername.company.local/ to resolve the name. Is there a setting in tunnel that I need to check for the phones to work? Not a huuge deal, but some of my users are very confused.

Hi there!
My name is Brandon, and I am glad to assist!

Computers, especially those joined to a corporate network or domain, or configured by IT, generally have what’s called a “DNS Suffix List” or “Suffix Search List” configured. On this list is often the configured company domains - like company.local.
This causes computers, when given only a hostname/, to search the DNS Suffix List for a match of hostname.company.local automatically.

If your workstations are domain joined, that domain is on the suffix list automatically and this may explain why it works on WARP if/when the workstations are not local.

For mobile devices, they generally are not joined to a domain in the same way, or they aren’t configured with that suffix list. A workaround for this would be, if the mobile devices are connected to your local network, to push a DNS Suffix/Search Domain with DHCP Option 119, which will allow you to add search domains to a DHCP Client request response.

If the mobile device is not on the local network, you may need to force the use of the fully-qualified domain name.

Hi Brandon,

Sorry for the late reply, the notification was stuck in Spam.
That seems likely, thank you very much for the reply.
