Microsoft Azure IP Lookup
Find network details, ASN, and IP range information for Microsoft Azure internet addresses.
Use our IP lookup tool to verify whether any IP address is associated with Microsoft Azure. Enter the IP address to get location, ASN, and VPN/proxy status instantly.
Open IP Lookup ToolAbout Microsoft Azure Network Infrastructure
Microsoft Azure is a major internet service provider operating IP address blocks allocated by regional internet registries. As an ISP, Microsoft Azure manages Autonomous System Numbers (ASNs) used in BGP routing to direct internet traffic across its network. IP addresses assigned by Microsoft Azure to customers are used to identify and route data across the global internet.
Our IP lookup tool identifies Microsoft Azure 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 Microsoft Azure's network infrastructure.
How ISP IP Ranges Work
Internet service providers like Microsoft Azure 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 Microsoft Azure, our tool queries the ASN database to identify the Autonomous System registered to Microsoft Azure and returns the associated network details including the geographic location of the IP block and contact information.

Frequently Asked Questions
What IP addresses does Microsoft Azure use?
Microsoft Azure operates multiple Autonomous Systems (ASNs) and IP address blocks. These are allocated by regional internet registries (ARIN, RIPE, APNIC). You can identify Microsoft Azure IP addresses using our IP lookup tool — enter any IP and check if the ISP field shows Microsoft Azure.
What is Microsoft Azure's ASN?
Microsoft Azure 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 Microsoft Azure's network. Use our IP lookup tool to find the specific ASN for any IP associated with Microsoft Azure.
How do I check if an IP belongs to Microsoft Azure?
Enter the IP address in our IP Lookup tool. The ISP and ASN fields will show whether the IP is registered to Microsoft Azure. You can also use WHOIS lookup to query the IP's network registration directly.
Does Microsoft Azure use VPN or proxy servers?
Microsoft Azure is a legitimate ISP and its customer IPs are generally not flagged as VPN or proxy. However, Microsoft Azure 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 Microsoft Azure IP addresses appear in different locations?
ISPs like Microsoft Azure 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.
