Did I configure my network right or do something redundant/unnecessary?
When I use a Arch Linux live boot disk to boot my computer the network works fine, but after I installed Arch on the system and booted natively, I had no connectivity. Eventually I stumbled my way to a working network using a static IP, but I am worried I may have done something unnecessary or redundant and am hoping for some expert comments. The different instructions I was working from the Arch Linux wiki and this site were not always clear cut and sometimes contradictory, so I had difficulty figuring out the definitive steps to configure the network. Here is what I did:
assume the root identity
run "lspci -v" to verify that a network driver was running (it was)
run "ip link". This revealed that the interface name was "enp0s31f6" and that it was "DOWN"
visited /etc/netctl and copied the static IP example out of the examples directory into the main netctl directory
modified the example file to include my IP address, gateway and DNS entries, renamed it to "my-network" and gave the command "netctl enable my-network"
tried "ip link". still DOWN
gave command "ip link set enp0s31f6 up". interface now is UP, but network does not work ("Network is unreachable")
gave the command "dhcpcd enp0s31f6" and network worked both for IP alone and DNS resolutions
So, I am confused about a couple of things. First, I thought that DHCP was for dynamic host resolution. Since I am using a static IP, not a dynamically assigned IP, why would dhcpcd work? What is it doing?
The other question is about config files. Above I describe the config file that worked. However, in the Arch Linux wiki it describes a different kind of config file that has a "[Match]" section and has a different format than the example file cited above. Also, in the wiki the directory shown is /etc/systemd/network/ not /etc/netctl as shown above. Why is there a completely different config system?
