Now you may run traixroute to see the IXPs in your path. Running traixroute for the first time takes a few minutes, as it has to perform a few initialization actions, downloading the datasets:
$ traixroute probe -dest cnn.com -s="-m 12" Dataset files are missing. Updating the database... Started downloading PDB dataset. Started downloading PCH dataset. Started downloading RouteViews dataset. Routeviews has been updated successfully. PDB dataset has been updated successfully. PCH dataset has been updated successfully.

This did not indicate any IXP in the path between my network and http://edition.cnn.com/. Let's try once more towards register.bg:
$ sudo traixroute probe -dest register.bg -s="-m 12" Imported 13 IXP Detection Rules from /configuration/rules.txt. Loading from Database. traIXroute using scamper with "-m 12" options. traIXroute to register.bg (192.92.129.35). 1) (62.4.224.1) 21.699 ms 2) (91.183.241.176) 7.769 ms 3) (91.183.246.114) 8.056 ms 4) (BNIX)->AS9002 (194.53.172.71) 7.417 ms 5) (87.245.234.130) 51.538 ms 6) (87.245.240.146) 51.324 ms 7) (178.132.82.126) 44.711 ms 8) (193.68.0.150) 46.406 ms 9) (193.68.0.181) 44.492 ms 10) (192.92.129.35) 44.777 ms IXP hops: 3) 91.183.246.114 <--- BNIX (BE,Brussels) ---> 4) 194.53.172.71
This shows that my request had an IXP hops (BNIX in Brussels) in between. If you repeat the request, you may notice that the IXP hops most certainly remained the same while other hops may have changed. You may repeat with other websites to see which IXPs that your network traffic passes through.
