Where do NAT IP addresses come from? Why no 10.0.2.* interface on host?

Hi all.

I have a new installation of 2.1 with a new KVM with Ubuntu 12 installed in it. The KVM's NIC is set to use NAT. Something assigned it an IP address of 10.0.2.15 and set its gateway to 10.0.2.2 and DNS server as 10.0.2.3.

(1) Where did those IP addresses come from? I don't see DHCP running in the Proxmox Debian host, nor do I see any DHCP configuration that defines the range of IP addresses that the NATed VMs will be assigned.

(2) How can I access the KVM (at 10.0.2.15) from the Proxmox Debian host when I don't see any NIC listed in ifconfig with a 10.0.2.* address. Proxmox has eth0 without an IP address and vmbr0 set with my real IP address, but there's no interface with an internal 10.0.2.* address.

Thanks
