Overview

Quick IP lookup, DNS lookup, MAC vendor lookup, and subnet calculator for IT/helpdesk techs. No tab-switching required.

NOC Toolkit puts the diagnostics you run every day in your browser toolbar — no more juggling five tabs across different lookup sites. FEATURES IP Lookup Check any IP address for city, region, country, ISP/org, ASN, and timezone — or fetch your own current public IP in one click. DNS Lookup Resolve A, AAAA, MX, TXT, NS, and CNAME records for any domain, instantly. MAC Vendor Lookup Enter a MAC address and instantly identify the hardware vendor — useful for spotting unknown devices on a network or checking what's actually connected. Subnet Calculator Enter an IP/CIDR (e.g. 192.168.1.0/24) and get the network address, broadcast address, netmask, wildcard mask, usable host range, and host count — calculated entirely on your device, no network request required. BUILT FOR THE DAILY GRIND If you work a help desk, NOC, or IT support role, this is the toolbar shortcut for the lookups you already do dozens of times a day. PRIVACY No accounts, no tracking, no analytics. IP, DNS, and MAC lookups are sent directly from your browser to the relevant lookup service (ipwho.is / Google Public DNS / macvendors.com) — this extension does not operate any servers and never sees your data.
