Bulk Geo IP Locator

Pasting IP addresses into a lookup page one at a time stops working the moment you export a list from a server log. The Kwebby Bulk Geo IP Locator is a bulk geo IP locator that takes up to 50 IP addresses, one per line, and returns the country, region, city, ISP and coordinates for each in a single pass. This guide shows what the tool returns, how to read the results and how far to trust them.

Key Takeaways

• The tool reads up to 50 IP addresses per run, one per line. The input label reads "IP Addresses (one per line, max 50)", and any lines after the 50th are ignored.
• Each result card shows the IP address, a country code, the city, region and country, the ISP and latitude and longitude. A "Download CSV" button saves the located rows as geo-ip-results.csv.
• A private or invalid address fails on its own card with a short message. The rest of the list still returns results.
• IP geolocation is an estimate. MaxMind puts country accuracy above 99 percent but city accuracy at 20 to 75 percent, so treat a city as a lead, not a fact.
• The results leave out postal code, time zone and ASN. Pair the tool with a blacklist check or a reverse IP lookup when you need more context.
• The tool is free and needs no account.

What Is the Kwebby Bulk Geo IP Locator?

The Kwebby Bulk Geo IP Locator is a free web tool that maps many IP addresses to locations at once. Paste a list, click Locate IPs and read one card per address. It replaces a series of single lookups with one paste and one click.

It belongs to Kwebby's Developer Tools. To check your own address first, open What Is My IP Address.

Key Features and How It Works

Up to 50 IPs, one per line

The input box opens with three example addresses: 8.8.8.8, 1.1.1.1 and 208.67.222.222. Replace them with your own list. The tool splits the text on line breaks, trims each line, drops blanks and reads the first 50.

A comma-separated list counts as one line, so put each address on its own row. For longer lists, work in batches of 50.

Location, ISP and coordinates for each IP

Each card starts with the IP address in monospace type and a country code on the right, such as US. Below it you see the city, region and country on one line, the ISP on the next and the latitude and longitude on the last.

IPv4 and IPv6 addresses both returned results when we tested the tool. The location data comes from the ip-api.com database, and duplicate addresses in your list are looked up once. In that run, 8.8.8.8 came back as Ashburn, Virginia, United States, with Google LLC as the ISP.

Row-by-row errors

A private or invalid entry returns a red message on its own card. In our test, 192.168.1.1 returned "private range" and a typo returned "invalid query". A network problem shows a single message above the results instead.

CSV export

After a lookup, the "Download CSV" button downloads geo-ip-results.csv. The file has seven columns: IP, Country, Region, City, ISP, Latitude and Longitude. Rows that failed to locate are left out of the file. Open it in Excel, Google Sheets or a database import.

The file holds every row, including failed ones. Delete rows where the location columns read "undefined" before you analyze the data.

Why Bulk IP Geolocation Matters

A single lookup answers one question. A batch answers pattern questions: which countries send the most requests, which ISPs appear again and again, and which logins come from regions you never serve. Those patterns drive decisions about blocking, fraud review and content targeting.

Accuracy sets the limit on those decisions. MaxMind, a geolocation data provider, describes IP geolocation as "an approximate location, not a precise one" and says it cannot identify a person's street address. Its published figures run from country accuracy above 99 percent, to 55 to 80 percent for state or province, to 20 to 75 percent for city.

Our own run shows the same caution. The tool placed Google's IPv4 DNS address 8.8.8.8 in Ashburn, Virginia, and its IPv6 DNS address in Montreal, Canada. Both belong to one operator. The result is the database's best estimate for each address, so read it as a pointer.

How to Use the Bulk Geo IP Locator

1. Open the tool and find the box labeled "IP Addresses (one per line, max 50)".
2. Replace the three example addresses with your own list, one IP address per line.
3. Click "Locate IPs". The button reads "Looking up…" while the request runs.
4. Read the "N IPs located" count above the results, then scroll through the cards.
5. Check every red card for the reason a lookup failed.
6. Click "Download CSV" to download geo-ip-results.csv for your spreadsheet.

Best Practices for IP Geolocation Work

Remove duplicates first

The tool does not merge repeated addresses, so duplicates use up your 50 slots. In a spreadsheet, use Remove Duplicates. In a terminal, run sort -u on the file before you copy the list.

Drop private addresses

RFC 1918 reserves 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 for private networks. Those addresses have no public location, and the tool returns "private range" for them. If your log shows only private addresses, the data came from inside a network or a proxy, and you need the forwarded address instead.

Treat city results as leads

Use the country as a reliable field and the city as a clue. Confirm anything important with a second signal, such as the ISP name, account history or the result of a Blacklist Lookup.

Expect VPNs and proxies

MaxMind notes that its country figure is highest when VPN usage is excluded. A visitor on a VPN appears where the VPN exits, not where the person sits. Flag unexpected locations for review rather than blocking on location alone.

Use the right input

The tool takes IP addresses, not domain names. To geolocate a website, resolve it with Domain Into IP first, then paste the address here.

Common Use Cases

• Server log review. Export unique IPs from an access log and see which countries and ISPs generate your traffic.
• Security triage. Map the sources of failed logins or bot-like requests, then check suspect addresses against a blacklist.
• Geo-targeting checks. Confirm that test visitors on different networks land in the regions your campaign targets.
• Fraud review. Compare the location of an order or signup with the billing country.
• Hosting audits. Look up the IPs behind a list of client or competitor sites to see where they are hosted.
• Link audits. Check where the servers behind a set of linking domains sit, then compare them with the Class C IP Checker.

Related Kwebby Tools

What Is My IP Address shows your own public IP and location. Domain Into IP turns domain names into IP addresses. The Reverse IP Domain Checker lists the domains that share an IP. Blacklist Lookup checks whether an IP appears on spam blacklists, and Find DNS Records shows the DNS entries behind a domain.

Final Thoughts

The Bulk Geo IP Locator turns a pile of IP addresses into a sorted picture of where traffic comes from. Trust the country, question the city and keep the batch clean of duplicates and private ranges. Export your next access log, paste the first 50 unique addresses and download the CSV. Then run the odd ones through Blacklist Lookup or the Reverse IP Domain Checker before you act.
