Hi In a current setup flow there are 3 ways of generating mac pool ranges: 1. Generated from the second and third parts of the first non-local IP:  {base MAC}:{IP part2}:{IP part3}:00-{base MAC}:{IP part2}:{IP part3}:ff 2. If (1) could not be done for some reason, we have default values in setup. 3. If (2) didn't work for some reason, the values are  left as created during DB creation. Assuming that we want (1) to work the best way possible, and to create "random" enough values for Mac Pool ranges, I would ask for an opinion for a better way. I am considering creating random int values instead of fetching the IP as it's simpler and safer than parsing 'ip a' output. Thanks. Alex Lourie Software Engineer in Integration Red Hat.
