To get a look at the low level DHCP configuration (Mac/Linux):ĭomain_name_server (ip_mult): Note: We are not just looking for the default but also for any VPN that overrides the public v6 address space. If you have IPv6 active the above should return at least one route (as per below) via a known interface such as “ en0 " on a Mac.ĭefault fe80:1e0b:a50:fbfe:d2f8%en0 UGcg en0 Netstat -rn -f inet6 | egrep -i "default|2000::/3" Note: We are not just looking for the default but also for any VPN that overrides the public v4 address space. For IPv6 we have a deep dive on how-to-fix-ipv6-connectivity/ but you can check on Mac or Linux with: IPv4 (inc. 254 depending upon the scope size) and this is where your computer sends all its traffic to be routed onwards. You get a default gateway like 172.27.250.144 (though they normally end in. Your default gateway is normally an automatically configured address via DHCP.

Additionally, this doesn’t give you any historical data (especially back when previous problems occured). Yet, for ‘non-techies’ to try and communicate these addresses, or even call out MAC addresses like 0f:32:b9:6a:64:f1, it can be error prone and gets complicated quickly.
