I'd like to find the IP range of the "Microsoft Corp" network provider.

How can I find this out? So far I've only been able to find this site which has a list of ip addresses, not necessarily an explicit range.

There is a related Stack Overflow question, but doing a "whois 157.56.237.102" on any whois site I've yet found doesn't give a range (have left a comment hoping for clarification)

I am concerned over what the motive of this question is. I can use my geo ip database, write a bit of code and extract a list from about a year ago but I am concerned what this list would be used for. –  closetnoc Feb 22 at 2:21
    
yes, I'm also curious. –  PatomaS Feb 22 at 4:03
    
To be specific. I have about 140 or so ip address ranges that I can extract. But I would want to make sure it is for a good purpose before I write code and post it publicly. –  closetnoc Feb 22 at 4:13
    
Thanks for the responses – this is a bit long winded, but I'm wanting to explore replicating the functionality of a google analytics View filter in a custom built javascript tracking application; the GA filter excludes certain bots from my View including the ones from the "Microsoft Corp" network provider. My idea was to find the IP range(s) that Google uses to ID "Microsoft Corp" –  Drewdavid Feb 23 at 4:48

There is no specific range for Microsoft. They are a company, a big one, with a lot of power, but still a company. What they have, are small blocks of IPs here and there on the countries where they have servers. There are many IPs related to Microsoft in the world.
