Bulk IP Lookup
Analyze up to 20 IP addresses at once. Get country, city, ISP, ASN, and geolocation in one table.
What Is Bulk IP Lookup?
Bulk IP lookup (multiple ip lookup or batch ip lookup) analyzes many IPv4 addresses in one request — country, city, ISP, and ASN per row.
VSPIC accepts up to 20 IPs per run for firewall log triage and abuse workflows without clicking each address separately.
How to Use This Tool
- Paste IPv4 addresses — one per line or separated by commas (max 20).
- Click Lookup All IPs to run batch ip lookup.
- Review the table: IP, country, city, ISP/org, and ASN.
- Note any failed rows and fix invalid addresses.
- Open single IP lookup or WHOIS for deeper detail on flagged IPs.
What Information Is Returned?
- IP
- Queried IPv4 address.
- Country
- Estimated country for the address.
- City
- Metro-level geolocation estimate.
- ISP / Org
- Network operator name.
- ASN
- Autonomous system when available.
Bulk IP Analysis Explained
Paste logs or CSV columns of IPs; the tool deduplicates valid IPv4 and queries in parallel.
Failed rows show errors so you can fix typos without rerunning the whole batch.
ISP and ASN Data
ASN and ISP columns help sort datacenter traffic from residential IPs in bulk ip checker results.
Pair with IP WHOIS for netblock contacts on suspicious ranges.
Geolocation Accuracy
Country is strongest; city may be wrong on VPN or mobile IPs. Use bulk results for triage, not legal proof of location.
Security Investigation Use Cases
- Correlate attacker IPs from SIEM exports.
- Label VPN/datacenter density in login logs.
- Prioritize abuse tickets by country and ASN.
Firewall Log Analysis
- Paste blocked connection IPs from daily syslog dumps.
- Identify scanning sources sharing one ASN.
- Feed high-risk IPs into blacklist checker individually.
Abuse Report Workflows
- Gather ISP and country for each spam source IP.
- Attach bulk table screenshots to provider tickets.
- Cross-check with reverse DNS on mail server IPs.
Benefits of Bulk IP Lookup
- Free ip address lookup bulk — 20 IPs per request.
- Table view for quick scanning.
- Same core data as single IP lookup.
- No install — browser-based batch ip lookup.

Frequently Asked Questions
Up to 20 valid IPv4 addresses per run — one per line or separated by commas or spaces.
Yes. Each IP uses the same geolocation and ISP databases as our standard IP lookup tool.
Copy the table from your browser or screenshot for tickets. JSON export may be added later.
Invalid IPv4, private ranges, or rate limits can cause per-IP errors while others succeed.
This bulk tool validates IPv4 only. Use IP lookup for individual IPv6 research where supported.
