Update an Amazon Route53 or Cloudflare record with your current public IP address.
Easiest way is to install AWS CLI from here and then configure the credentials executing aws configure and provide access key and secret key for an IAM user with enough permissions to update the Route53 hosted zone.
Set a Cloudflare token in CLOUDFLARE_API_TOKEN environment variable or create a proper configuration file ~/.cloudflare/cloudflare.cf
