Use Microsoft Flow to receive an email for changes to Office 365 IP Addresses and URLs

This is really nice, but I have to ask: can't Microsoft just mail out updates to a subscriber list like everyone else?

I'm really trying not to be sassy, but I just took about a thousand rows from a web page and filtered it down to 192 IPv4 addresses that we might care about, and couldn't help noticing that (1) there's a lot of duplication; (2) no shortcuts come out of that, because the networks range in size from /12 to /32 and (3) there's little correlation between a product and the IP networks its servers inhabit. Might I suggest that MS take all the servers for one product and group them in three or four /18s, take all the servers for the next and do the same? That way my Office365 ACL could be a dozen lines rather than 192. And here comes someone telling me how I can write a routine in Yet Another Scripting Language to extract information that the vendor could just email to me. Thanks, but....
