IPs-LE
Find every IP address, CIDR block and MAC address in a tree, normalized and classified.
The command-line tool and its MCP server are written and tested. The VS Code extension is not written yet, so there is nothing to install from the Marketplace or Open VSX — those links appear here when it ships rather than before.
No editor in the loop? ips-le mcp runs the same engine as an MCP server, so an agent can call extract_ips over stdio, with no editor and no Node, and cargo install ips-le puts the same check in a terminal. Every way to install it.

What IPs-LE does
A regex over dotted quads finds no IPv6 at all, calls 1.2.3 an address, and reports 2001:0db8::0001 and 2001:db8::1 as two different things when they are one. IPs-LE finds every IP address, CIDR block and MAC address in a tree, normalizes IPv6 per RFC 5952, and says what each one is: loopback, private, link-local, cgnat, multicast, broadcast, reserved, documentation, unique-local or global. The scan runs over the bytes of every file, so an address inside a connection string or a rotated log is found too. It never resolves a name, never geolocates and never opens a socket.
What people use it for
Audit an allow-list
Filter to private and loopback and see what a config makes reachable that the change request never mentioned.
Surface an SSRF bypass
A leading-zero octet is octal to some resolvers and decimal to others, so 010.1.1.1 is refused by name rather than resolved to either.
Make a diff stop lying
Four spellings of one IPv6 address sort as four entries in raw text and as one after normalization.
Install IPs-LE
Command lineComing soon
cargo install ips-leNot on crates.io yet — v0.1.0 builds from the repository today, and this command starts working the day it publishes. Follow the repository.
VS CodeComing soon
ext install nolindnaidoo.ips-leThe extension is not written yet, so this id resolves to nothing on the Marketplace. It is the id it will take. Follow the repository.
Cursor / VSCodiumComing soon
cursor --install-extension OffensiveEdge.ips-leSame again for the forks, which resolve Open VSX rather than the Marketplace. Follow the repository.
Zed
ips-le mcpWorks in Zed today — add the command above as a custom MCP server from the agent panel, and extract_ips appears in its tool list. There is no one-click listing in Zed's extension registry yet.
AI agents
ips-le mcpRuns IPs-LE's engine as an MCP server over stdio, so an agent can call extract_ips with no editor and no Node. The binary is the server — there is nothing else to install.
Where it ships
One engine, 6 places to get it. The ids differ by registry — copy the one for the editor you use.
