A comprehensive package for pulling nearly all details of Linux networking into reliable and broadly usable form. From configuration to statistics, NetSnap uses the fastest available api: RTNetlink and Generic Netlink. NetSnap can fuction in either standalone fashion generating JSON output, or provide Python 3.8+ objects. NetSnap provides deep visibility into network interfaces, routing tables, neighbor tables, multicast databases, and routing rules through direct kernel communication via CFFI. More maintainable than alternatives as NetSnap avoids any hard-coded duplication of numeric constants. This improves NetSnap's portability and maintainability across distros and kernel releases since the kernel running on each system is the 'single source of truth' for all symbolic definitions.

In use cases where network configuration changes happen every second or less, where snapshots are not enough as each change must be tracked in real time, or one-time-per-new-kernel CFFI recompile time is too expensive, consider alternatives such as pyroute2.
