What it is for

Allow or identify traffic from a specific Azure region.

$curl -s https://proxyspace.pro/ip-ranges/azure.txt

Microsoft Azure IP ranges: questions

How many IP addresses does Microsoft Azure use?

The official list has 12,655 IPv4 prefixes covering 51,807,785 addresses and 5,060 IPv6 prefixes, in 78 regions; the largest is eastus with 5M IPv4 addresses.

How often does the Microsoft Azure IP list change?

ProxySpace fetches it every day; the source was last updated on 2026-11-02. Rules built from it should be refreshed regularly, for example with a daily cron job that downloads the list again.

How do I check whether an IP belongs to Microsoft Azure?

Download the list and match the address against it, or use the IP lookup tool to see the network (ASN) an address belongs to.

Where are the IP ranges of other networks?

See the IP ranges page for every cloud provider and every country, or the Tailscale page for the 100.64.0.0/10 range.
