How to update a MySQL table with data from itself

Suppose I want to update a MySQL table with data that refers to the same table. To make it easier to follow along, I will use the following actual WordPress administration scenario.

Here is my configuration file using Intel Compilers

IPv6 and IPv4 name resolution with Go

As part of a work-related project, I'm writing code that needs to resolve DNS names using Go, on illumos.
