This organization I’m working for uses OpenDNS/Cisco Umbrella. I’m confused as to why I’m seeing requests for SSL traffic resolved to
18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206
Are these sinkholed IP addresses? I thought the blockpage IPs were these ones: https://support.opendns.com/hc/en-us/articles/227986927-What-are-the-Cisco-Umbrella-Block-Page-IP-Addresses-
I guess I’m just confused as to how this whole thing works. I’ve tried reading the OpenDNS support but it hasn’t really answered my questions on the IPs above.
I’ve tried setting up OpenDNS with netplan via the following two methods. And they don’t work. I know because I issue the command
sudo netplan try and I get an error.
sudo vi /etc/netplan/50-cloud-init.yaml # Put this in the body nameservers: addresses: [220.127.116.11, 18.104.22.168] # Save, exit, then `sudo netplan try`
…or this. Note that my internet is WiFi, not ethernet, not sure if that’s the issue with my syntax.
sudo vi /etc/netplan/50-cloud-init.yaml # Put this in the body network: ethernet: wlo1: nameservers: addresses: [22.214.171.124, 126.96.36.199] # Save, exit, then `sudo netplan try`
How do I setup OpenDNS with netplan? I know my link right here explains it, but that’s for older Ubuntu and doesn’t work anymore. I can’t even open
Network Connections on Ubuntu 18.04. I think
Network Connections GUI is deprecated.
