Holy moly that's a lot.

There's a couple of flaws with a "distinct IP" count:

1. Not all servers get updated (I know of 3 or 4 CentOS servers that
probably haven't been updated in months.
2. One machine can get multiple IPs
3. Many machines can look line one IP

However, distinct IP does give us a rough estimate of installs.  And
even if it's off by 30% one way or another - it's a bigger number than
I thought.
