    If you didn't put that line in /etc/resolv.conf, then probably it
    was configured by DHCP client, which used the information send by
    your DSL modem.
    That would explain "attlocal.net" lines.
    Do you have administrative access to your DSL modem's configuration
    web interface?
    Or is it a leased device that was configured by your ISP and you
    don't have the option to configure it?
    
    If you have the access to DSL modem, you can configure its DHCP
    server to always send proper DNS server addresses, like "1.1.1.1",
    "8.8.8.8", instead of "192.168.1.254".
    Alternatively, and if you don't have the access to DSL modem, you
    can modify "dhclient.conf" file to effectively override name server
    addresses sent by your modem with known good ones.
    This procedure is described in Debian Wiki. [1]
    Basically, all you have to do is add at the end of the file this
    string:
        supersede domain-name-servers 1.1.1.1,1.0.0.1,8.8.8.8,8.8.4.4;
