Doing a reverse lookup for every goddamn IP I ever see would be completely impractical.
Hyperbole much? Recognizing IPv6 addresses is not that different from recognizing IPv4 ones, especially if you assign local parts manually, which you should do for the servers instead of relying on autoconfiguration, for reasons which should be obvious. So, 2001:db8:0:1001::4 is...?
- 2001:db8::/32 is your organization's prefix. You're supposed to know it by heart.
- 0:1001 is, say, Accounting. You know your network's addressing plan, right?
- ::4 is their print server.
With a bit of practice, parsing the IPv6 addresses you deal with frequently will become second nature. If it doesn't, then maybe you're not such a hot network admin.
