I'm assuming that you entered something like this in a router: ip route 63.182.182.182 255.0.0.0 where = an interface name or IP address of a neighboring router. If this is an accurate assumption when you do a "show run" you'll probably see the following instead: ip route 63.0.0.0 255.0.0.0 This would explain why you're sending these other packets to 63.x.x.x to la-la land. Do a trace and see where the packets are going to confirm what I'm saying. Note: On more recent versions of IOS the router will complain and tell you that you have an "inconsistent address and mask." -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Telemachus Luu Sent: Wednesday, November 07, 2001 3:37 PM To: [EMAIL PROTECTED] Subject: Subnet Mask question [7:25602] Hi, Can someone provide a good explanation to this? Imaginary IPs: Static host ip: 63.182.182.182 mask: 255.255.255.0 I accidently specified an incorrect mask of 255.0.0.0. However, I was still able to ping some sites out in the net but was unable to ping a host in the same class, eg. 63.221.133.4. 1. Why was I able to ping out even though the mask specified was incorrect? 2. Why was I unable to ping the host in the same class? thanks, Telemachus Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=25694&t=25694 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
