nscheck gives bad; opendns.com/welcome good...?;(

my lan has three routers serving one AP: that is, two are configured as repeaters. it all works swell locally.

I configured the primary /host AP for opendns. the simple check at opendns.com/welcome shows good.

nslookup shows confusion: primary nameserver = localhost;

for this type of arrangement, is there anything else I need to do? are these results normal for a "bridged" lan?

You do not configure APs, but you configure the DNS settings at the router, at the router/place where all DNS queries must pass, ideally on the WAN side, not on the LAN/DHCP side. DNS is rather unrelated to the transport method (e.g. radio waves or cupper cable).

"nslookup shows confusion: primary nameserver = localhost"

I would have to see more. Can you post the complete plain text outputs of the following diagnostics from a computer where it doesn't seem to work:

nslookup -type=txt debug.opendns.com.

And in case of Windows: ipconfig /all

Also, the diagnostic URL is http://welcome.opendns.com/ (which redirects to another page depending on the result).

I'm using the term AP generically - I have three routers in a common AP [two as repeaters]. the check page looks good.

1.2.168.192.in-addr.arpa
        primary name server = localhost
        responsible mail addr = nobody.invalid
        serial = 1

Well, "DNS Servers . . . . . . . . . . . : 192.168.2.1" is the plain truth, not "nslookup shows confusion: primary nameserver = localhost".
Where did you get this localhost information from?

After all, your issue is a non-issue, everything looks fine. You're using the OpenDNS Dallas data center, and your IP address 70.120.87.151 is registered with OpenDNS network ID 27249780. Your computer uses your router at 192.168.2.1 as DNS server/forwarder where you must have configured the OpenDNS resolver addresses.

"I'm using the term AP generically" - Oops, this is confusing for readers...

"How do I send that nslookup to a text file?"

As with every other command prompt window output: you mark the text in question, right-click to copy to the clipboard, and paste it to where you want it to be.

Ah, I see were you got the localhost information from:

1.2.168.192.in-addr.arpa
        primary name server = localhost
        responsible mail addr = nobody.invalid
        serial = 1
        refresh = 600 (10 mins)
        retry   = 1200 (20 mins)
        expire = 604800 (7 days)
        default TTL = 10800 (3 hours)
Server: UnKnown
Address: 192.168.2.1

Well, this 192.168.2.1 is a private IP address, and your router is stupid enough to send a DNS query for itself also outside to a public DNS service (OpenDNS) instead of responding with whatever hostname. And exactly the above is what OpenDNS returns. What else should they return? What would be the right hostname for 192.168.2.1 ?

nslookup 192.168.2.1 208.67.220.220
Server: resolver2.opendns.com
Address: 208.67.220.220

1.2.168.192.in-addr.arpa
        primary name server = localhost
        responsible mail addr = nobody.invalid
        serial = 1
        refresh = 600 (10 mins)
        retry   = 1200 (20 mins)
        expire = 604800 (7 days)
        default TTL = 10800 (3 hours)

oh, and that menu/command thing doesn't work on a Lenovo x120. never did.

it marks fine, but pressing right click unmarks everything. It did copy just using ctrl+c

"ok, so no problem, eh?"

Yes, no problem. Everything here was good for essentially nothing. :(

"it marks fine, but pressing right click unmarks everything."

...and copies it to the clipboard. Yes, with the right-click the marking disappears. But it's waiting in the clipboard then to be pasted. This is how Windows works, independent from any hardware being used.
