Microsoft Azure IP Lookup

Microsoft Azure operates the following Autonomous System Numbers (ASNs): AS8075, AS8068, AS8069. Microsoft Azure operates AS8075 (Microsoft Corporation) across 60+ cloud regions; Microsoft publishes weekly Azure IP range lists on the Microsoft Download Center — these IPs are heavily monitored by enterprise firewalls and SIEM tools. Use our IP lookup tool to identify which specific ASN a Microsoft Azure IP belongs to.

Microsoft Azure holds multiple IP address blocks allocated by its regional internet registry. These blocks are announced via BGP under AS8075 and AS8068 and AS8069. You can identify Microsoft Azure IP addresses using our IP lookup tool — enter any IP and check if the ISP/ASN fields show 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 (look for AS8075 or AS8068 or AS8069). You can also use our WHOIS Lookup to query the IP's network registration directly from the RIR database.

Microsoft Azure provides internet services in: Global (60+ regions). As a cloud/CDN provider, Microsoft Azure uses anycast routing meaning its IPs appear to originate from the nearest data center to the user.

Microsoft Azure is a cloud/data center provider. Its IP ranges are routinely flagged as 'data center' or 'hosting' by IP reputation services. Many VPN providers, proxies, and automated bots use Microsoft Azure infrastructure, so these IPs are often scored as high-risk by fraud detection systems.
