Hello @Devon
Akamai Net is a 3rd Party hosting provider, meaning that any of the websites or applications you use or access may use Akamai for storing their files. For example, you are browsing looking for your next holiday destination, or your favorite social network, even if you are in an specific URL website their content may be stored in Akamai's cloud storage.
The general recommendation is to disable traffic to that domain, so you can see how this is affecting you. There is an old trick to use the HOSTS file as a redirection to invalid DNS for specific addresses in order to block the traffic out.
