Microsoft also now publishes this data as a JSON and RSS and change log
available from

The IPs have changed a few times since the document’s inception, so I
cross referenced the documented O365 IPs with ARIN’s database.  I then
chose to implement the CIDR as defined by ARIN  (YMMV).

In the past I've pulled down an XML file that included the IP space for
all of the O365 products.  Then I filtered, sorted and aggregated what I
wanted for my internal use via a script.

Sorry, I should have stated that I have already searched, and have seen
the above mentioned docs as well as everything else on the first page of
the search results.



I guess what I was looking for was to see if somebody has already
consolidated that list in to something easier to work with.

I think it is cool that companies take the time and effort to publish
such useful lists. Keep it up!

Kind regards,
