ping: network unreachble although I have an IP through DHCP [closed]
Clash Royale CLAN TAG#URR8PPP
I am about to install Archlinux on a root server via VNC. For installation Archlinux needs an internet connection. If I run ip addr it seems to me that I get an IPv6 address via DHCP (every reboot it's a different one, but all are fe80::/64). Here is the output:
sh
$ ip addr
1: lo [uninteresting, so skipped]
2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 52:54:01:00:00:28 brd ff:ff:ff:ff:ff:ff
inet6 fe80::b056:977e:546c:1d41/64 scope link
valid_lft forever preferred_lft forever
I enabled and started dhcpcd manually, but the output remains the same. The problem is that I cannot reach any outside server. Pinging 8.8.8.8 or the IPv6 pendant 2001:4860:4860::8888 prints that the network is unreachable. I tried out some tips with revolv and rc.conf that I found while googling for some solution, but nothing worked so far, especially since I do not know anything about the provider's network architecture.

You do not have an IP address with which you can explore the outside world.
If you want to access 8.8.8.8, you will need an IPv4 IP address. That will show up as something like:
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether dc:a9:71:04:30:ee brd ff:ff:ff:ff:ff:ff
inet 192.168.178.20/24 brd 192.168.178.255 scope global wlan0
valid_lft forever preferred_lft forever
in your ip addr output. So no IPv4 address.
You also do not have an IPv6 address that you can use in the outside world. Your FE80-address won't make it past your first router. You probably do not have an IPv6 router on your network (at least, not one that uses stateless autoconfig).
Your logs also indicate that your dhcpcd does not get an IP address. From the comments, I understand that your provider should give you an IP via DHCP. Although a router can do DHCP, almost everyone in a larger network uses a separate DHCP-server. That allows them to keep central control over the IP addresses and it is also easier to automatically update their DNS. We use Infoblox, but there are others as well.
All that the router does is convert your DHCP request broadcast on the local lan to a unicast towards your DHCP server. (it is bad habit to refer to your own website, but https://ljm.home.xs4all.nl/dhcp/index.html gives a bit of an explanation)
