Tools to Obtain and Work with Cloud Provider CIDR Blocks

Description

Cloud providers will be added on an as-needed or request basis (i.e. if you need another cloud provider, file an issue or — prefereably — PR).

Some cloud providers provide either an API or a file that contains all of the public networks that make up their cloud infrastructure. Many force you to obtain this data from publicly available internet routing registration data. Tools are provided that provide a standard API to obtain the network information for supported cloud providers. Each provider function returns processed, raw data structures that can be normalized with additional functions to enable predictable and consistent data formats for further processing.

A future plan is to memoise the results and also provide disk-level caching since these CIDRs don’t change frequently enough to warrant network traffic for each call.

What’s Inside the Tin

The following functions are implemented:

• all_ranges: Build a complete data frame of all known cloud provider ranges
• amazon_ranges: Amazon AWS cloud ranges
• azure_ranges: Azure ranges
• digitalocean_ranges: Digital Ocean ranges
• google_ranges: Google Cloud ranges
• linode_ranges: Linode ranges
• normalize_ipv4: Normalize Cloud CIDR return values
• ovh_ranges: OVH ranges
• rackspace_ranges: Rackspace ranges
• softlayer_ranges: Softlayer ranges
