I have bypassed DNS on occassion by just typing in the IP address in the URL address box in the browser (98.139.135.21 or 98.139.135.22), but this returns "Bad request" for me, so it looks like the server is a virtual server or parses the request somehow. Several websites probably use the same IP address and the website returned is dependent on other data in the request, such as the server (www) or domain name (kelinginc.net or kelinginc.com). For me "ping"ing: "... kwallace@910:~$ ping kelinginc.net PING kelinginc.net (98.139.135.22) 56(84) bytes of data. 64 bytes from sbsfe-b.geo.vip.bf1.yahoo.com (98.139.135.22): icmp_seq=1 ttl=50 time=127 ms 64 bytes from sbsfe-b.geo.vip.bf1.yahoo.com (98.139.135.22): icmp_seq=2 ttl=50 time=126 ms 64 bytes from sbsfe-b.geo.vip.bf1.yahoo.com (98.139.135.22): icmp_seq=3 ttl=50 time=125 ms 64 bytes from sbsfe-b.geo.vip.bf1.yahoo.com (98.139.135.22): icmp_seq=4 ttl=50 time=124 ms ^C --- kelinginc.net ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 124.572/126.251/127.989/1.307 ms kwallace@910:~$ ping www.kelinginc.net PING sbsfe.geo.mf0.yahoodns.net (98.139.135.21) 56(84) bytes of data. 64 bytes from sbsfe-a.geo.vip.bf1.yahoo.com (98.139.135.21): icmp_seq=1 ttl=50 time=128 ms 64 bytes from sbsfe-a.geo.vip.bf1.yahoo.com (98.139.135.21): icmp_seq=2 ttl=50 time=130 ms 64 bytes from sbsfe-a.geo.vip.bf1.yahoo.com (98.139.135.21): icmp_seq=3 ttl=50 time=147 ms 64 bytes from sbsfe-a.geo.vip.bf1.yahoo.com (98.139.135.21): icmp_seq=4 ttl=50 time=116 ms ^C --- sbsfe.geo.mf0.yahoodns.net ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3001ms rtt min/avg/max/mdev = 116.900/130.999/147.841/11.035 ms kwallace@910:~$ ... " If one gets the same result, my guess is that DNS is okay, but something else in the browser request is bad. (?) I forgot how but there may be a way to add the domain name to the IP address in the browser address box. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Got Input?
