The IPv4 addresses being logged are not accurate (or stable).
The following requests were made from from the same computer (should be 192.168.1.135)

(I think someone else in the gemini mailing list had this problem, I'm not sure if they said what server they were using).

Can confirm: on gmnisrv master, commit cb2c84b0.

All of the following IPs should be from 198.54.132.172. I restarted 
gmnisrv in the middle for good measure:

204.196.198.54 seirdy.one / 297ms  1559 20 text/gemini

[ I restart gmnisrv ]

loaded certificate for seirdy.one
loaded certificate for localhost
listening on [::]:1965
listening on 0.0.0.0:1965
217.82.198.54 seirdy.one / 962ms  1559 20 text/gemini
217.108.198.54 seirdy.one /about/ 512ms  3377 20 text/gemini
217.182.198.54 seirdy.one /music.txt 654ms 11849 20 text/plain


Thanks for your work.

I have also observed this on IPv6 - which made me think addresses are
intentionally obfuscated for privacy. Is this by design?

Is there any benefit to obfuscating IP addresses for privacy rather than 
omitting them entirely? The mechanism, let alone the rationale, seems 
rather unclear.

If anybody knows more about this than I do, documentation would be 
appreciated.
