Network Utility, removing a Whois server
I was using Network Utility to discover its capabilities. All options appear to work as expected and are quite useful except the Whois and Finger tabs. I finally discovered my firewall was blocking my whois queries by giving almost instant timeout errors. However In the process I've added a lot of unnecessary Whois servers [and non-Whois servers] to my Whois server list. Does anyone know where this list is kept so I can either delete some or wipe it completely and add the correct ones? I'm using MacOS 10.13.2 & Network Utility 1.9.2 (114). Thanks
