Update DHCP Custom nameservers for 100+ devices

[tblanchard]

We have 100+ devices (MX68-HW) and we need to update the "Custom nameservers" located here:

Security & SD-WAN > DHCP > Custom nameservers

Is there a way to do this without having to change it manually one-by-one?  We are trying to write a python API script, but no luck yet.

Thanks for your help!

The options for this are limited to either API or Manual unless your networks are bound to a Configuration Template which would then allow you to modify this setting at the template level instead of managing this at the network level. 

For the API calls you can use the GET/PUT Network Appliance VLANs in order to build your script. The linked document also has a sample JSON output to help build out your script.
