Basically its not possible, DNS is concern, u can add 2 IPs in A record address record) in Resorce Record. we call it as "Poor Mans Load Balancing" techinally its called "ROUND ROBIN" so in Round Robin, first time u hit the DNS ..for IP address u will get first IP address, Second time when u hit u will get Second IP address. its round robin.... If the Second ip address or either one of the ip address is down, then DNS won't know about it...as in DNS rfs....there is not solution ..then..u have rewrite the DNS protocol :-(. pluz the software.... Now, if these IPs are in same Subnet...then..u can. ..when ever one of IP is goes down....u add the the that IP address to live one...which means..one machine has two IPs... If its nots...rewrite the packet....and port no....using linux clusters...etc..etc...if ur intersted.. plz go to below link... http://lcic.org/load_balancing.html jai ----- Original Message ----- From: upendra gandhi <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, August 28, 2002 1:37 PM Subject: [LIH]dns ??? !!!! > hi all > i gotta q'nhere it is > see i got domain name www.upen.com > i have 2 ips > a and b > now initially www.upen.com points to b > when b goes down due to some prob then i want dns to > point www.upen.com to 'a' > how do i achieve this???? > > ===== > upendra gandhi CIW ASSOCIATE (Server Admin.Internetworking Professional, Security Professional) > http://home.graffiti.net/upengan78 [EMAIL PROTECTED] [EMAIL PROTECTED] > [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] > > "THE LIVING GOD IS WITHIN YOU" Dearest 'swami vivekananda' > > __________________________________________________ > Do You Yahoo!? > Yahoo!
