Summary
Microsoft Corporation
enterprise legacy
MICROSOFT-GP-AS is one of the many autonomous systems registered to Microsoft Corporation in Redmond, Washington. It is a small, largely dormant AS, not one of Microsoft's production cloud networks.
What it's used for
AS6584 currently announces no IPv4 space at all. Its only announcement is a single IPv6 /48 carved out of 2a01:110::/32, RIPE-registered space whose parent block is named for Microsoft's corporate IT organisation rather than for Azure. Microsoft's public-facing cloud and content traffic rides on other numbers, chiefly [AS8075](https://asn.ipinfo.app/AS8075).
Notable
An address in this AS is corporate-IT space, not cloud-hosting space. Anyone reasoning about Microsoft address space should be careful which Microsoft AS they are looking at, because the company operates dozens of them and they are not interchangeable.
The -GP- in the handle is a business-unit fossil of the kind that survives in ARIN records long after the unit itself is renamed or absorbed. ARIN registered the number in May 1996; Microsoft is the registrant of record today.
