As noticed by some in the Internet network operations community, at the beginning of May an odd event occurred as ICANN ended DNS service on the IP address formerly associated with L.ROOT-SERVERS.NET (”L-root”). Specifically, as ICANN turned off the DNS service at the address formerly used by the L-root, 198.32.64.12 (and the routing announcement by ICANN for 198.32.64.0/24), DNS root queries sent to that address instead of the new L-root address (199.7.83.42) continued to be answered.
