Why each option
The address 10.10.10.10, being a private IP address on the internal network and likely the original source address of a host, is classified as an inside local address in the context of NAT.
An outside global (OG) address is a public IP address of a device on the outside network, typically the final destination address, which 10.10.10.10 is not.
An inside global (IG) address is a public IP address representing an inside local address to the outside world, post-NAT translation, and 10.10.10.10 is a private address.
An outside local (OL) address is the actual IP address of a device on the outside network, as seen from the inside network; 10.10.10.10 is typically on the *inside* network before translation.
An inside local (IL) address is the private IP address assigned to a host on the inside network before any NAT translation. Since 10.10.10.10 is a private, RFC 1918-compliant address, it perfectly fits the definition of an inside local address.
