Bulk IP Lookup
Paste a list of IP addresses (one per line or comma-separated) to look them all up at once.
About the Bulk IP Lookup tool
Looking up addresses one at a time is slow when you have a whole list - from a firewall log, an analytics export or a block list. This tool takes many IPs at once and returns a row for each: whether it is IPv4 or IPv6, the country and network/ASN it belongs to, and any reverse-DNS hostname. You can paste addresses one per line or comma-separated, and mix both formats.
How to use it
- Paste your addresses into the box, for example
8.8.8.8and1.1.1.1on separate lines. - Submit to look them all up in a single pass.
- Read the per-IP results and copy or scan the table.
It is built for triaging access logs, enriching a spreadsheet of addresses, or grouping traffic by network and country. As with single lookups, the geolocation is an approximation tied to the network, not a precise location, and very large lists may be capped or take longer to process. The addresses you paste are sent to our server only to compute the results, and are not stored.
Frequently asked questions
What format should I paste the IP addresses in?
Either one IP per line or comma-separated, and you can mix the two. Both IPv4 and IPv6 addresses are accepted in the same list.
Is there a limit to how many IPs I can look up at once?
Very large lists may be capped or take a little longer to process so the service stays responsive. For big batches, split the list and run it in a few passes.
What does each result row include?
For every address you get its type (IPv4 or IPv6), the country and owning network with its ASN, and any reverse-DNS hostname, so you can scan the whole set at a glance.
How is this different from the single IP Lookup tool?
It returns the same per-IP details but processes a whole list in one request, which is far faster than pasting addresses individually when triaging logs or block lists.
