Azure IP Lookup

Find Azure service tag, region, and network metadata for any IP address or domain. Share results easily with a link to the same lookup.

Frequently asked questions

How does the Azure IP Lookup tool work?
The lookup submits your IP address or domain to the Azure IP Lookup API. The API maps the address to Azure service tags published by Microsoft and returns the matching service tag ID, region, and network feature metadata. Results update weekly as Microsoft releases new IP data.
Does the lookup support IPv6 addresses?
Yes. The tool accepts IPv4, IPv6, and domain names. IPv6 prefixes are returned exactly as Microsoft publishes them in the weekly service tag downloads.
What are Azure service tags?
Azure service tags group IP ranges for Azure services. Instead of maintaining IP allowlists, you can reference a single service tag in your NSG or firewall rules. Each service tag has an ID and network features that describe its usage.
How often does Azure update IP data?
Microsoft publishes updated IP ranges weekly. Use the Azure IP Ranges and Service Tags – Public Cloud download to stay current.
Can I automate lookups?
Yes. The Azure Speed IP Lookup API accepts a simple GET request at /api/ipAddress?ipOrDomain=<ipAddressOrDomain> . Supply either an IP address or domain name and the service returns the same payload you see in the UI.
