Ronen,
Traceroute over IPencap should work. You may need to ensure the TTL is 64 for your encapsulated routes.
Your tunnel packets might be inheriting the TTL from some other interface like an IPV6 one.

Hello Steve,
Are you connected via an IPIP tunnel? This looks like you have native 44/8 connectivity via BGP. Back to the larger conversation, an IPIP tunnel is just that, a TUNNEL and exposure to the intermediate hops to provide end to end connectivity are usually hidden. Some tunnel encapsulations have options to resolve this such as GRE - https://utcc.utoronto.ca/~cks/space/blog/tech/TranslucentGRE .
You might be able to fake this out with Hping2 though: http://inet-access.net/pipermail/list/2003-October/000575.html
For example, tracing to router.db0fhn.ampr.org (not 100% is this the correct IP to use or not but you get the idea) -- sudo hping2 -0 -H 4 -d 10 --traceroute router.db0fhn.ampr.org
