# Networking

Functions in the **Networking** category of the Studio `fx` menu parse and transform IP addresses, URIs, HTTP
payloads, and protocol fingerprints.

Start with everyday IP and URL work:

- [IP Address In CIDR Range Check](./ip-address-in-cidr-range-check/) — test whether an IP belongs to a subnet.
- [Change IP format](./change-ip-format/) / [Parse IP range](./parse-ip-range/) — convert or expand address ranges.
- [Defang URL](./defang-url/) / [Defang IP Addresses](./defang-ip-addresses/) — make links and IPs safe to share.
- [Parse URI](./parse-uri/) — split a URL into scheme, host, path, and query.

Common HTTP and fingerprint helpers:

- [Strip HTTP headers](./strip-http-headers/) / [Dechunk HTTP response](./dechunk-http-response/) — isolate or reassemble
  bodies.
- [JA3 Fingerprint](./ja3-fingerprint/) / [HASSH Client Fingerprint](./hassh-client-fingerprint/) — TLS and SSH client
  fingerprints.
- [Parse User Agent](./parse-user-agent/) — identify browser and OS from a user-agent string.

Open a function page from the sidebar for parameters, returned values, and examples. The transform functions overview
also summarizes this category.
