TXT Records: Usage

Ok..the last DNS question. I've been on a DNS kick lately. So when poking around, I keep bumping sites that have txt records all with cryptic, but yet similar text in them.. Something like:

cnn.com.		3305	IN	TXT	"882269757-4422010"
cnn.com.		3305	IN	TXT	"ms=ms97284866"
cnn.com.		3305	IN	TXT	"688162515-4422037"

What are these for? I keep getting referred to SPF for sending email, but it doesn't seem right.. who looks at these numbers? CNN alone has like 25 TXT records all with these types of numbers.

TXT can hold about any text, so new things can get stuffed in there. SPF I think has a record now but still lives in TXT as well for old implementations. I've seen it also hold DKIM (another email spam thing), ssh fingerprints, DNS-SD (Service discovery), and just any plain ol' text you want. I don't recognize your example as being anything useful though, but a quick Google shows the ms=msXXXX entry seems to be for Microsoft Office 365
