IP address not being picked up via DHCP

Recommended Posts

I'm mainly posting this so that people with the same problem might find this via Google:

 

Symptom:

You have registered your Ultimaker S5 for network access via its ethernet port using its MAC address to assign a specific IP address. However it does not pick up the IP address and instead assigns a self assigned 169.x.x.x address. 

 

Problem:

Some older / enterprise DHCP servers do not like you having an associated DNS if it starts with a number. 3D printers my be more prone to this if like me, you created a DNS "3dprint.myorg.com".

 

Solution:

If you do have a DNS associated with your 3D printer, make sure it doesn't start with a number or have a network that sucks less than ours.

Oh my!  That's interesting.  @nallath is Ultimaker aware that DNS names that start with "3D" may be a problem for the UM3 and S5?  I would be surprised that Unix cares about this but I suppose it's possible.
