    DhcpStressTest

    • Originally developed for the WIZ820io which has some ARP/DHCP bugs which necessitate special recovery techniques in code
    • DHCP lease time (on my router) is set to 120 seconds, the minimum allowed by the Asus RT56NU router, and it appears to allow renewal at 1/2 that, or every 60 seconds.
    • This enables 24 * 60, or 1440 DHCP renewals in 24 hrs vs a more typical one or two. This compresses one or two years of DHCP renewal into 24 hours.
    • Versions for Teensy3 with WIZ850io and the Arduino.org (not the same as Arduino.cc) M0 Pro with WIZnet W5500 Shield
    • Logs for this test
