How to Look Up Any IP Address or Domain

Enter any IP address or domain name to see its location, ISP, timezone and ASN — domains are resolved to an IP first, automatically.

To look up any IP address or domain, open IP Address Lookup, type or paste it in, and press enter. If you give it a domain name, the tool resolves it to an IP address first, then shows that address's location, timezone, internet provider and network details — all in one result.

What this tool does

IP Address Lookup takes a single IP address or domain name and returns what's publicly known about it: approximate location, timezone, postal code, and network information like the ISP, organization and ASN (the number that identifies the network it belongs to). It's the same kind of lookup as What Is My IP, except you control what gets looked up instead of it always being your own connection.

Give it a domain name instead of an IP, and it does one extra step first: it resolves the domain to its A records (its IPv4 addresses) using a DNS-over-HTTPS query, lists those, then runs the full lookup on the first address it gets back.

How to look up an IP or domain with Toolbench

  1. Open IP Address Lookup.
  2. Type or paste an IP address (like 8.8.8.8) or a domain name (like example.com) into the input box. The tool only reads the first non-empty line, so pasting multiple lines just uses the first one.
  3. If you paste a full URL (https://example.com/page?x=1), the tool strips the https:// and everything after the domain automatically — you don't need to clean it up first.
  4. The result appears automatically — there's no separate "go" button to click.
  5. Click Copy to copy the result, or use Send to → to pass it into another tool.

A real worked example

Enter an IP address directly, like 8.8.8.8, and the tool returns a result built entirely from that address's network data — fields like IP, Version, City, Region, Country, Postal code, Coordinates, Timezone, ISP, Organization and ASN, each only printed when a value for it was actually found.

Enter a domain name instead, and two extra lines appear first, showing the resolution step before the lookup:

Domain       example.com
A records    192.0.2.1

IP           192.0.2.1
Version      IPv4
...

(192.0.2.1 above is a placeholder — it's part of the 192.0.2.0/24 block that RFC 5737 reserves specifically for documentation examples, not a real address. When you run the tool yourself, the Domain and A records lines show the real IP address or addresses your browser's DNS query resolved, and everything below them is that address's real location and network data.) If a domain has more than one A record, all of them are listed on the A records line, separated by commas — the lookup itself still runs on just the first one.

What each field means

Field What it shows
Domain / A records Only shown for a domain input — the hostname you entered and the IPv4 address(es) it resolved to
IP The address that was looked up
Version Whether it's IPv4 or IPv6
City, Region, Country Approximate location, to city or region level
Postal code, Coordinates Approximate postal code and latitude/longitude, when available
Timezone The local timezone for that location, with its UTC offset
ISP The internet service provider that owns the address
Organization Only shown when it's different from the ISP — many addresses report the same name for both
ASN The autonomous system number identifying the network the address belongs to

Tips and common mistakes

  • A domain can resolve to more than one address, or to different ones over time. Large sites often spread traffic across several IPs or use a CDN, so looking up the same domain tomorrow can return a different address than it does today.
  • A domain that doesn't resolve returns an error, not a blank result. If the DNS lookup finds no A records, the tool reports that it couldn't resolve the domain instead of guessing.
  • The tool only reads the first line you type. If you paste something with multiple lines, anything after the first non-empty line is ignored.
  • The IP you look up belongs to a connection, not necessarily a single server or person. Many sites sit behind shared hosting, CDNs or proxies, so the ISP and location shown may belong to the infrastructure in front of the actual server.
  • Looking up your own connection is a separate, simpler tool. If you just want your own public IP, What Is My IP shows it automatically with no typing required.
  • What Is My IP — see your own public IP, location and ISP automatically, with no input needed.
  • Password Generator — another quick step toward staying more secure online.

Frequently asked questions

Can I look up a domain name instead of an IP address?

Yes. Enter a domain name and the tool resolves it to its IPv4 address (or addresses) first, shows those A records, then runs the full location and network lookup on the first address.

Does it work with IPv6 addresses?

Yes, when you enter an IPv6 address directly. The Version field in the result reports whether the looked-up address is IPv4 or IPv6.

Why do I see "Organization" sometimes but not always?

The tool only prints an Organization line when it's different from the ISP name. Many addresses report the same value for both, so the line is left out rather than repeated.

Is the location exact?

No — it's an IP geolocation estimate, typically accurate to city or region level. It maps address ranges to the location they're registered or believed to serve, which can be off for mobile, satellite or corporate connections.

Does Toolbench store the addresses or domains I look up?

No. Each lookup runs fresh in your browser against a public IP lookup service (and, for domains, a DNS-over-HTTPS query) at the moment you enter it — nothing about it is saved by Toolbench, signed in or not.
