tcpdump Updated 2025-07-16
To test it, let's get two computers on the same local area network, e.g. connected to Wi-Fi on the same home modem router.
On computer B:
- find computer IP with the
ipCLI tool. Suppose it is 192.168.1.102 - then run Ciro's
ncHTTP test server
Output on terminal 1:TODO understand them all! Possibly correlate with Wireshark, or use

CIA 2010 covert communication websites ipinf.ru Updated 2025-07-16
alljohnny.com had a hit: ipinf.ru/domains/alljohnny.com/, and so Ciro started looking around... and a good number of other things have hits.Not all of them, definitely less data than viewdns.info.
But they do reverse IP, and they show which nearby reverse IPs have hits on the same page, for free, which is great!
Shame their ordering is purely alphabetical, doesn't properly order the IPs so it is a bit of a pain, but we can handle it.
OMG, Russians!!!
