My advice (regarding the IP addresses) is:

 - where you have https://tools.ietf.org/html/rfc1918 addresses, leave them as 
they are - you're not giving away any sensitive information by telling us 
about your internal addresses which can't be routed over the Internet

 - where you have public addresses and would prefer not to reveal what these 
are, substitute with https://tools.ietf.org/html/rfc5737 addresses instead.

 - always ensure that you substitute address A in the same way each time, and 
address B, etc.
