    DNS Suffix Search List


    Was poking around this AM to see if my DNS server selection could be improved or if it was ok. After Running Gibson's DNSBench.exe several times, convinced me I was already on the "best" one (openDNS).

    When I did an IPconfig /all, I am looking at something that has puzzled me for a while and that is DNS Suffix Search List is listed as T-Mobile.com1?

    OpenDNS is set on my computer, as well as in the Wan DNS1/2 on the router. I am using a Tmobile/ASUS TM-AC 1900 and T-Mobile.com1 is listed as the router Domain name?

    Appreciate any clarity on this...Tx

    If you have automatic DNS provisioning set up in your TCP/IP properties (see this article: http://compinfopro.com/dns-suffix-what-does-it-mean/) it's probably getting its initial DNS info/access through the router, and that's where the domain name and initial lookup is originating. That said, if it's working properly and you're happy with its performance and behavior, remember the old saying "If it ain't broke, don't fix it!"

    You're welcome. Hope it all starts making some kind of sense soon! If not, I wrote a TCP/IP textbook that I can recommend. It's now in it's 5th edition, so it must be OK.
