The IP address 10.0.2.15 is the default address for the slirp (user-net)
support integrated inside qemu.
slirp does not need any configuration nor external tools.
It does *not* forward ping (ICMP) packets but it works with TCP
connections as it were a NAT (masquerading) router.

So if the guest os gets the address, it is able to resolve names, it is able
to ping 10.0.2.2 (the default route) everything should be okay.
If it resolves google.com but you cannot ping it... it is the standard
behavior.

P.s. I have my experience on qemu for linux, but for user-net netowrking 
should behave in the same way.
