Store IP Ranges in Redis as sorted sets for fast retrieval
pip install iprange-python
from iprange import IPRange
iprange = IPRange()
# Add a new range with some metadata
iprange.add('192.168.0.1/24', {'some': 'data', 'more': 'metadata'})
# Find the most specific range that contains a specific IP
iprange.find('192.168.0.20')
# => {'range': '192.168.0.1/24', 'some': 'data', 'more': 'metadata'}
# Find all ranges that contains a specific IP
iprange.find_all('192.168.0.20')
# => [{'range': '192.168.0.1/24', 'some': 'data', 'more': 'metadata'}]
# Delete the range
iprange.remove('192.168.0.1/24')You can use it with Redis Cluster too:
from iprange import IPRange
# Requires at least one node for cluster discovery. Multiple nodes is recommended.
startup_nodes = [{'host': '127.0.0.1', 'port': 16379}]
iprange = IPRange(redis_cluster=True, startup_nodes=startup_nodes)
# ...This library relies on a Redis fork that implements interval sets, as described in this blog post.
You can also use a more recent version of Redis with Interval Sets.
