Hi everyone, today I have discover a critical network infrastructure which is almost impossible. I believe very few people have seen this before.
The story is .... in my office we have leased internet connection with static IP from TATA Communication Ltd. In my local network I have configured network ip (192.168.7.0). So all the PC in my local network has the IP of the range 192.168.7.1 to 192.168.7.253. For a experimental purpose yesterday I have ping to 192.168.2.10... It should not return reply. But unfortunately I got reply from a host. After investigation I have found that the host is outside of my local network. Please look into the tracepath report from my local PC to that unknown host. nirmalya@nirmalya-desktop:~$ tracepath 192.168.2.10 1: nirmalya-desktop.local (192.168.7.103) 0.141ms pmtu 1500 1: 192.168.7.51 (192.168.7.51) 0.706ms 1: 192.168.7.51 (192.168.7.51) 0.700ms 2: 115.115.147.137 (115.115.147.137) 150.228ms 3: 121.240.2.54 (121.240.2.54) 188.099ms asymm 6 4: 121.240.2.57 (121.240.2.57) 175.322ms asymm 6 5: 172.25.81.133 (172.25.81.133) 176.625ms asymm 6 6: 172.29.253.34 (172.29.253.34) 208.708ms asymm 8 7: 172.31.16.193 (172.31.16.193) 186.462ms asymm 8 8: 172.31.35.138 (172.31.35.138) 206.554ms asymm 10 9: 172.31.8.134 (172.31.8.134) 226.454ms asymm 10 10: 172.25.82.62 (172.25.82.62) 206.389ms asymm 9 11: 192.168.2.10 (192.168.2.10) 217.967ms reached Resume: pmtu 1500 hops 11 back 247 In this report 192.168.7.103 is my personal PC, 192.168.7.51 is internal IP of router, 115.115.147.137 is gateway IP of our leased internet connection. I have already reported it to TATA Communication Ltd. They give us commitment to solve it by 24hour. Have anyone see this before? --- [Nirmalya Lahiri] + - [+91-9433113536] _______________________________________________ Ilugd mailing list [email protected] http://frodo.hserus.net/mailman/listinfo/ilugd
