ipterm
ipterm.net is a "what's my IP" site that works like a terminal, in your browser and from
curl. Look up your own address or any IP, network, domain, mail setup or port. No accounts, no cookies, no tracking.
Try it
curl ipterm.net # just your IP
curl ipterm.net/me # your IP, network and rough location on a Braille world map
curl ipterm.net/line # IP, network, country and data center on one line, for a prompt or tmux
curl ipterm.net/8.8.8.8/org # one value for any address
curl ipterm.net/8.8.8.8/text # everything about an address, as aligned text
curl ipterm.net/mail/gmail.com # SPF, DMARC, DKIM and MTA-STS, graded A to F
curl ipterm.net/grade/github.com # a domain's report card: DNSSEC, email, expiry and security headers
curl -4 ipterm.net/port/22 # is a port open on your own IP?
curl ipterm.net/help # everything else
In Windows PowerShell, type curl.exe: plain curl there is Invoke-WebRequest.
With documentation values instead of a real address. In a terminal the land is green and your location is lit;
?w=$COLUMNS fits it to your terminal, ?color=0 turns colors off and ?redact hides the IP for screenshots.

In the browser
ipterm.net is the same thing as a terminal: type help, or click any command. Every result has
its own page to share (ipterm.net/8.8.8.8, ipterm.net/AS13335, ipterm.net/dns/example.com), and [share] [copy] [md] on its header line, where md copies it as a Markdown block for an issue or a chat. Tab completes, Ctrl+R
searches your history, and ipterm.net/go?q=<anything> works as a browser search engine.
| Command | What it does |
|---|
whoami | your IP, network and approximate location |
leaktest | a VPN and DNS leak test, graded A to F on leaks only: which DNS servers look up sites for you, WebRTC and IPv6 leaks, your time zone, VPN detection (Cloudflare WARP, Tor, iCloud Private Relay, and servers on VPN providers' own lists by name). share copies an IP-free link to the grade |
lookup <ip, domain or ASN> | owner, network and location of any address, and whether it's a VPN or relay (including servers on Mullvad's, PIA's, IVPN's and AirVPN's own lists, and Apple's iCloud Private Relay addresses); a domain's DNS records |
dig <name> [type] | one DNS record type, with TTLs |
whois <ip, ASN or domain> | the registry record, over RDAP |
mail <domain> | email security (MX, SPF, DMARC, DKIM, MTA-STS, TLS-RPT, BIMI), graded A to F |
grade <domain> | a domain's report card, graded A to F: DNSSEC, IPv6, CAA, email, expiry and transfer lock, the redirect to HTTPS and the security headers. copy badge gives a README badge drawn by shields.io, so your readers never contact ipterm |
port <number> | is a TCP port open on your own IP? It never tests any other address |
cidr <range> | subnet calculator, IPv4 and IPv6 |
Privacy
- No accounts, no cookies, no analytics, no ad scripts. ipterm's code stores and logs nothing about visitors.
- Cloudflare, which hosts it, keeps its own records of the traffic: the site's owner sees it mostly in aggregate
(countries, paths, user agents), plus a sample of individual requests with their IP, from up to the last 31 days.
Browsers may also send Cloudflare network error reports (NEL).
- The page's Content-Security-Policy is
default-src 'none': scripts and styles come only from ipterm itself, and the
only other hosts it may fetch from are ipify (to show your other IP version) and ipterm's own DNS leak test zone.
leaktest also asks Cloudflare's STUN server which addresses WebRTC reveals.
- Your own address goes to a data provider (IPinfo, proxycheck.io) only when you run
leaktest.
- Known VPN servers come from the server lists Mullvad, PIA, IVPN and AirVPN publish, and iCloud Private Relay's
addresses from Apple's list, which ipterm downloads every six hours. Lookups are checked against its own copy, so
no address is sent to them.
- One labeled affiliate line (Proton VPN) appears after a leak test whose VPN check ran and found no VPN. It's a plain
link, and never appears in
curl output.
The full privacy policy says what each part sees. Every page's footer links to this
repository, and names the exact commit that's running when the site is deployed with npm run deploy.
How it's built
One Cloudflare Worker (src/worker.js) and a vanilla JavaScript page (public/), with no build step. Your own
address comes from Cloudflare's edge, other addresses from IPinfo, networks from RIPEstat,
registry records over RDAP, DNS from Cloudflare's 1.1.1.1, and known VPN servers and iCloud Private Relay addresses
from the providers' own published lists, refreshed by a cron trigger (src/vpn-lists.js, src/relay-list.js). The DNS leak test has its own small DNS server on a VPS
(dnsleak-server/).
Run your own
npm install
npx wrangler login
npm run deploy
Then set SELF_HOSTED = "true" in wrangler.toml: your copy marks itself noindex, shows no sponsored line and says
in its footer that it's a copy of ipterm. Everything else is in the handbook: the settings and
optional keys (IPinfo, proxycheck.io), the budgets and rate limits, every route and check, security and local
development. The DNS leak test server has its own guide: dnsleak-server/README.md.

Natural Earth (public domain). IP address data powered by IPinfo.
