  2. How do find out the IP Address,default router, primary dns,secondary dns, and A wep key


  3. There is tools on Unix Environments like “SystemV ,BSD,LINUX”
    The tool is “tracerout” !
    is a very good to find any DNS server .

  8. Hi chevin, please read last line of entry by ivor painin debutt then go to the top of the page. The information is there.

    Could cause you future problems if you don’t know how to deal with the information! Then, of course, your query might not relate to the information here in which case you need to be more open with what you really want to ask as we cannot help you otherwise.

  9. Hey, im currently using my ps3 for the internet, i have recently been using the wi-fi one minute it was fine, next minute it said i have been disconntected from the access point. It was failing to obtain my IP address so i have bought the ps3 into the front room to find it on the internet, once i found my IP address now i have the infamous 80710102 error for my DNS

    I used a DNS site to find the codes for it, It gave me my primary but not my secondary i really need to find it. I cant access the main computer of the household it is password locked and i cant access the internet on my own computer (dads rules, hes paying for it he chooses if i have access)

    Is there any sites out there that will give me the secondary DNS code? Thank you :)

  10. Everyone with a PS3…
    Thers are 2 pairs of DNS server adress’ at the top of the page. Choose either and enter the datails thats it. Don’t be scared of DNS because it’s an anacronymn.

  15. To anyone who can help. Goin through a not nice separation. My soon to be ex-husband is a super computer head. He manages all the networks. I think he has managed to block my internet access on my computer, which he can’t access.
    When I try to connect, It is says ‘unable to connect to Primary DNS server’. Is there anyway I can over ride this. Broadband connection very bad where I live. Sorry inexperienced, but a quick learner.

  16. omg my ps3 gt all errors i need a gd dns i changed mine and now i have problem to sign in to psn .help plz

  17. Thanks again Vivek!

    You could again show something new.

    Other hand – just one more probably worth a mention.
    Comodo – provides safe dns servers.
    The same comodo with the free av and free firewall.
    Albeit it is a filtered one – just like opendns is – to prevent you from explicit adult material and from viruses (?) too (?)

    Go and find the ip for yourself. ;-)
