I get warnings like this when I use nios_fixed_address as well (on 2.9.15).

Task:

- name: make a host record
  nios_fixed_address:
    name: my-record-4.example.com
    ipaddr: 192.168.100.4
    network: 192.168.100.0/24
    mac: 00:00:00:00:00:00
    provider:
      host: nios.example.com
      username: admin
      password: infoblox
      validate_certs: no

Output:

TASK [make a host record] **************************************************************************************************************
[WARNING]: Both option ipaddr and its alias ipaddr are set.
[WARNING]: Both option mac and its alias mac are set.
[WARNING]: Both option network and its alias network are set.
ok: [localhost]

Same behavior, works as expected, but throwing warnings about aliases. Seems to me that aliases are set in the module code when they shouldn't be.
