How accurate are Geolocation tools, I don't need them to be accurate to the last millimeter, I just need to make sure they are in the right continent at the very least. I ask this because I understand that sometimes the owner of the block of IP's may be in (as an example) Microsoft USA but the IP's may be physically in the UK. Will this confuse the Geolocation tool into thinking they are in fact physically located and being used in the US ??
Some background of why I'm asking this question
I have the most laborious task of classifying and sorting out our "what's up gold" monitoring system in relation to our O365 traffic. The netflow module allows you to classify traffic (it has to be the worst implementation of this feature I have seen on any monitoring system).
You can only put one port per subnet which means multiple instances of the same port pointing to multiple subnets which is a really backward way of doing things. Now you can imagine how many O365 addresses there are which makes this an excruciating task especially when I have to show which Region the IP's are which just triples the work...
