Mac Devices Register DNS with Generic Hostnames on WiFi but Correct Names on Wired Connection

Hi Jamf Community,

We're experiencing an interesting DNS registration issue with our Mac fleet that I'm hoping someone might have encountered before.

Issue Description

When our Mac devices connect to our corporate WiFi network, they register in DNS (Infoblox) with generic names like mac.domain or macbook.domain instead of their proper hostnames (e.g., mbp-dav.domain). However, when these same devices connect via Ethernet cable, they register correctly with their actual hostnames.

Environment Details

  • DNS/DHCP: Infoblox
  • Mac devices: Various models running macOS
  • All Mac devices have proper hostnames configured

What I've Verified

I've confirmed the hostname settings are correctly configured on the affected devices:

System preferences show the hostname is correctly set in the Mac's configuration, and I've checked the DHCP packets which don't seem to include any hostname options that might cause this behavior.

 

Questions

  1. Has anyone else encountered this issue where Macs register differently on WiFi vs. wired connections?
  2. Are there specific settings in Jamf or on the Mac that could address this inconsistency?
  3. Could this be related to how the Mac's mDNS/Bonjour services interact with Infoblox on different network types?

Any insights or suggestions would be greatly appreciated. Thanks in advance for your help!

@__AMM Have you checked with Infoblox support? I think this is a know issue.
