you may need to edit the /etc/hosts file.there may be problems with dnsmasq and systemd-resolved on your 18.04 computer.your router may not be setup to use the DNS servers that you desire.I have some experience with this, but I'm by no means an expert. GlobalĪnyone know how to get my nslookups to start using the DNS specified here? And how the heck did that comcast stuff get in there and how do I get it out? Here is the output from systemd-resolve -status showing a ton of junk in the GLOBAL section and showing the DNS on the router at 192.168.1.1 but that appears to be ignored based on the lookups shown above. # run 'systemd-resolve -status' to see details about the actual nameservers. # 127.0.0.53 is the systemd-resolved stub resolver. # DO NOT EDIT THIS FILE BY HAND - YOUR CHANGES WILL BE OVERWRITTEN Here is the contents of my nf file: # Dynamic nf(5) file for glibc resolver(3) generated by resolvconf(8)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Here is the results of ifconfig showing my last interface is my wifi and is connected to the correct network: enp2s0: flags=40Įther 28:f1:0e:4a:a4:b2 txqueuelen 1000 (Ethernet) It has its own DNS and things worked great until updating to Ubuntu 18 now none of my local machines resolve (all not found) when I do an nslookup. 90% of the time I connect to the internet through my home router and comcast is not listed in the config at all for it. I am confused on how to fix this or even how it came to be.
