Hi all,
I just tried a reverse dns lookup on whoismydns.com for my wife's computer on a family-member's network.
Result: DNS Server: 67.231.208.167 Reverse DNS: pub-cdns3-wlfdle-eth1.rpub.net.rogers.com IP Owner: Rogers
Does this seem correct? I have my dns settings set on my machine and I get my expected DNS results on my machine on this family member's network. Is there any reason to be concerned here?
I had noticed a while back, before upgrades on this family member's network, that utopia.net was being used as the DNS server. It was on more than one machine that used that network. Now I'm wondering if somehow this network was routing, in a still-problematic way, but just via a local address?
I may have confused some concepts as I am just getting my feet wet with this topic of DNS servers.
If anyone has suggestions to confirm if the network is properly setup, please let me know.
Why are you looking up the DNS, when you want to look up your wife's computer? Look up her WAN address. Her host name should be something like cpe<router MAC>-cm<modem MAC>.cpe.net.cable.rogers.com. Host name changed to protect the guilty. ;-) She should also have IPv6 addresses.
