Is there way to avoid duplicating ip when massive parallel registration (about 50) happens?

curl -s -H 'Authorization: Bearer <TOKEN>' http://localhost:8081/api/nodes/main| jq -c '.[].address'| sort -h| uniq -c

output

1 "10.96.0.1"
2 "10.96.0.10"
1 "10.96.0.11"
1 "10.96.0.12"

I run ansible playbook with

serial:1

to make queue for run

netclient join

. It works. As I understand Netmaker API can't manage to registration queue. Like this

- hosts: netclient 
  serial: 1
  roles: 
    - { role: netmaker/client/join, tags: join }
