So usually, if I wanted to view the connections currently being made by my mac, I would use sudo lsof -i to get a list of processes and ip addresses. However, I have noticed something odd, especially with this site, macrumors. While the network tab of the developer tools for firefox list the ip addresses and domains, for some reason these sometimes do not appear when I run sudo lsof -i.
For macrumours especially, I can see all the loaded assets and their domain and ip addresses using the developer tools. However, these ip addresses never appear when I run sudo lsof -i, or sudo lsof -ni. However, for as far as I can tell, this does happen for every other site.
So is there a reason why this is occurring? As far as I am aware, there should be no reason why the command would ignore or not display certain ip addresses or domains. Before anyone asks, yes I am sure it is not caching them, as they are not listed as cached in the firefox developer tools, and I have cleared my browser cache.
