Open IP Lookup ToolAbout SoftBank Network Infrastructure
SoftBank is a major internet service provider operating IP address blocks allocated by regional internet registries. As an ISP, SoftBank manages Autonomous System Numbers (ASNs) used in BGP routing to direct internet traffic across its network. IP addresses assigned by SoftBank to customers are used to identify and route data across the global internet.
Our IP lookup tool identifies SoftBank IP addresses by matching IP ranges against the MaxMind GeoLite2 ASN database. This allows security teams, network administrators, and developers to quickly verify whether traffic originates from SoftBank's network infrastructure.
How ISP IP Ranges Work
Internet service providers like SoftBank receive large blocks of IP addresses from their regional internet registry (ARIN in North America, RIPE NCC in Europe, APNIC in Asia-Pacific). These blocks are divided into smaller ranges and assigned to customers, data centers, and network infrastructure.
When you look up an IP from SoftBank, our tool queries the ASN database to identify the Autonomous System registered to SoftBank and returns the associated network details including the geographic location of the IP block and contact information.

Frequently Asked Questions
What IP addresses does SoftBank use?
SoftBank operates multiple Autonomous Systems (ASNs) and IP address blocks. These are allocated by regional internet registries (ARIN, RIPE, APNIC). You can identify SoftBank IP addresses using our IP lookup tool — enter any IP and check if the ISP field shows SoftBank.
What is SoftBank's ASN?
SoftBank operates one or more Autonomous System Numbers (ASNs) registered with the regional internet registry. ASNs are used in BGP routing to identify and route traffic for SoftBank's network. Use our IP lookup tool to find the specific ASN for any IP associated with SoftBank.
How do I check if an IP belongs to SoftBank?
Enter the IP address in our IP Lookup tool. The ISP and ASN fields will show whether the IP is registered to SoftBank. You can also use WHOIS lookup to query the IP's network registration directly.
Does SoftBank use VPN or proxy servers?
SoftBank is a legitimate ISP and its customer IPs are generally not flagged as VPN or proxy. However, SoftBank also operates data center infrastructure that may be associated with hosting services. Cloud arms of major ISPs (like AWS, Azure) have their own IP ranges that are often flagged as data center IPs.
Why do SoftBank IP addresses appear in different locations?
ISPs like SoftBank operate networks across many geographic regions, assigning IP blocks to regional infrastructure. The same ISP name may appear for IPs in different cities or states because large ISPs manage nationwide or global networks from centralized infrastructure. The location shown is based on the IP block's registered location, not the user's precise address.
