High network usage

[jaimeferj]

I was very surprised about the network usage for this container:

Is this normal? Because I do not see any reason why this network bandwidth would be taken for updating a dns.

My docker-compose.yml:

  cloudflare-ddns:
    image: timothyjmiller/cloudflare-ddns:latest
    container_name: cloudflare-ddns
    security_opt:
      - no-new-privileges:true
    network_mode: "host"
    environment:
      - PUID=$PUID
      - PGID=$PGID
    volumes:
      - ./config.json:/config.json
    restart: unless-stopped

My config.json:

{
  "cloudflare": [
    {
      "authentication": {
        "api_token": "whatever"
      },
      "zone_id": "whatever",
      "subdomains": [
        {
          "name": "whatever",
          "proxied": false
        }
]
}
  ],
  "a": true,
  "aaaa": true,
  "purgeUnknownRecords": false,
  "ttl": 300
}
