POST http://netbox.lutech.lab/api/ipam/ip-addresses/ not working

[bbird81]

NetBox version

3.1.7

Python version

3.8

Steps to Reproduce

Use the POST method for creating a new ip address

Expected Behavior

A new ip address should have been created

Observed Behavior

Netbox always returns "200 OK" with the list of current ip address already present in the IPAM module.

Tried many ways to add an ip address from API:

• using pynetbox nb.ipam.ip_addresses.create method
• using requests to POST on http://netbox/api/ipam/ip-addresses/
• using Insomnia to build the POST

I also tried to copy examples from others (which I assume work for them), but no luck for me...

Can you show the exact command and body, e.g. using curl? If you're getting back a 200 with a list of IP addresses, it seems Netbox thinks you're doing a GET and not a POST as you expect.

I would suggest you run tcpdump to be 100% sure. On the Netbox server:

tcpdump -i eth0 -nn -s0 -A tcp port 8001

Replace eth0 with your interface name (ip addr list to find out). This should show the plaintext traffic between your frontend webserver (Apache or Nginx) and the Netbox gunicorn process.

Hit Netbox with the request. There will be a bunch of garbage mixed in which is the TCP/IP headers, but buried in this you're expecting to see:

POST HTTP/1.0 /api/ipam/ip-addresses/
Host: netbox.example.com
... more headers

and then the JSON POST body content, possibly in a subsequent packet or packets.
