DNS Port Randomness Test

One of my DNS servers has been upgraded from Bind 9.4.2 to Bind 9.5.0-P1 in order to circumvent the cache posioning problem due to the lack of randomness in port numbers. The test string and the server for testing the randomness can be found at https://www.dns-oarc.net/oarc/services/porttest.

After the upgrade, the port randomness problem is resolved.
