When running a traceroute, should I see any public IP addresses when tracing route from one MPLS point to another MPLS point? So when I do a traceroute from 10.0.0.1 to 10.0.1.1, I see some public IP address in between…
On some of the routers I see this, on others I don't, what does this mean?

That depend on your MPLS provider. so there are a patch for the traceroute program, that print the MPLS label using ICMP, if the LSR is configured to affich these labels ( but most of providers don't do). You may test the NANOG traceroute normalized in RFC 4950
