Free IP Address Lookup Tool

This online tool helps domain buyers map a public IP address to network context: resolve A/AAAA for public IPs, then ASN, internet service provider (ISP), and geolocation data from DB-IP Lite. No API key needed on the free tier.

Paste an ip address or hostname, a URL, or a public IPv4/IPv6 value. Address dns records (A and AAAA) resolve first, then DB-IP Lite enrichment. A private IP such as 192.168.x.x is not given public location fields.

How to use this IP lookup tool

Use this IP lookup tool when you need the addresses behind a domain name, or the IP address location and ASN of an IPv4 address you already have. One target per run.

  1. Enter an IP address or domain name above (for example example.com or 8.8.8.8). URLs are accepted too.
  2. Click Lookup IP. For a name we resolve A and AAAA records; for a pasted address we enrich results with DB-IP Lite and reverse PTR when published.
  3. Read the IP list or detail card: country and city-level IP location, ASN, organization, and PTR when published.
  4. Need MX, NS, TXT, and the full zone? Open DNS Lookup. Registration data stays on WHOIS Lookup.

What you get

  • Addresses — every IPv4 (A) and IPv6 (AAAA) we resolve for the name, or the IP address you pasted.
  • Network context — country, region, and city from DB-IP Lite, plus ASN and organization (ISP, host, or CDN).
  • PTR — reverse DNS when one is published.
  • Your IP address — shown on the page without typing it.

ASN, enrichment, and what this ip checker shows

This ip lookup service ties a hostname or internet protocol address to routing context—useful when internet traffic should reach a host, but never as proof of who sits behind the keyboard.

Addresses behind a name

Enter a domain and we read A and AAAA rows. CDNs often publish several values; an IP address in the table may be an edge node, not the origin. Paste one IPv4 or IPv6 target to skip resolution.

Location information and ASN

Geo ip rows (country, region, city) use DB-IP Lite and similar ip location databases—city-level geographical location, not GPS. Each ASN announces a range of ip addresses within its address space; organization text usually names the ISP or CDN, not the site brand.

Limits, WHOIS, and full zones

We do not flag VPNs or proxies. Public targets only—private LAN blocks are rejected. Registration on WHOIS Lookup; other record types on DNS Lookup.

Frequently Asked Questions

What does this tool show?

Resolved A/AAAA values for a name, or DB-IP Lite context for a pasted target: country/region/city, ASN, organization, and PTR when published. Each IP address row is independent. Your IP from this visit appears above the form.

Where does the data come from?

Public resolver answers for A, AAAA, and PTR, plus DB-IP Lite for ASN and city/region fields. We do not invent coordinates.

How accurate is IP geolocation?

We show an approximate location at city or region level—not an exact location, street, or household. Treat each row as network geography only.

What is the difference between IPv4 and IPv6?

IPv4 is four numbers separated by periods (for example 8.8.8.8). IPv6 is a 128-bit address written in hex. We support both via A and AAAA.

Can this detect a VPN or proxy?

No. If you go through a proxy server or VPN, we show that exit IP and its location—not your real IP. ASN/org text may name a host or CDN.

Can I query a domain and a numeric target here?

Yes. Names resolve first; pasted numbers skip straight to enrichment.

Why several rows for one site?

Load balancing, anycast, or a CDN edge. Multiple answers are normal.

Is there a daily limit?

No signup on the free tier: 1 target per run and the shared free daily domain limit of 10 per day (name or number = one unit).

How is this different from your full-zone checker?

Our DNS Lookup returns MX, NS, TXT, and more across four resolvers. This page focuses on addresses plus DB-IP Lite context.

How can I run more checks after the free daily limit?

Upgrade to the Pro plan for higher limits inside Karma.Domains.

Is there a Chrome extension?

Yes — the Karma Domains Chrome extension adds age and Karma Metric on SERPs and runs Checks from the popup.

Where can I browse expired domains to buy?

Alongside this free check, the full list of expired domains from 49 lists across 32 platforms (auctions, drops and buy-now listings) is on the Karma.Domains homepage, updated hourly.
