Sometimes ISPs assign their internal routers an IP in this address range (192.168.*.* / 10.*.*.* / etc). These addresses aren't uniquely addressable (i.e. you can't "ping" them from various locations and expect either a response, or a response from that particular host.) The routers (especially border ones) are supposed to be configured NOT to route these private ranges, so it is ok for them to use a non-public address on these routers. ~ ).(. -----Original Message----- From: Vineet Mehta [mailto:vineet () linux com kw] Sent: Monday, April 07, 2003 4:20 AM To: pen-test () securityfocus com Subject: Traceroute Question Hi all, While trying to do traceroute on one of the server i get the following reply: $traceroute a.b.c.d 1 192.168.0.254 (192.168.0.254) 0.442 ms 0.397 ms 0.358 ms 2 62.150.42.1 (62.150.42.1) 1.951 ms 1.315 ms 1.249 ms 3 172.17.8.149 (172.17.8.149) 43.577 ms 23.481 ms 17.653 ms 4 border.qualitynet.net (195.226.227.1) 19.935 ms 20.902 ms 21.896 ms 5 isp.qualitynet.net (195.226.227.10) 19.928 ms 23.302 ms 21.839 ms 6 192.168.226.38 (192.168.226.38) 71.321 ms 282.457 ms * My Question is why I am getting 192.168.226.38 non-route able address output in traceroute reply?
