I've been having network issues and I noticed that my traceroutes were looking a bit weird considering I'm connected directly to my modem, which goes straight to the cable.

Is it normal for the first hops to look like that? The setup is literally my computer connected to the modem which goes to the post.
Thanks.
tracert -j
can be used to see the reverse route. Unfortunately, source routing has a great potential for abuse, and therefore most network administrators block all source-routed packets at their border routers. So, in practice, Loose Source Routes aren't going to work.
