Is this a valid IP Address?
For each IP, you can select whether it's invalid, private, public or special.
"Private" means the usual big blocks, no /24 documantation subnet or anything like that
"Special" means valid and specifically mentioned in an RFC as being "for something" (like CG-NAT, loopback, classes D & E etc.)
