Yes, if you are running a double-stack (IPv6+IPv4) machine, in which the
two protocols are simultaneously available.
No, if you have IPv6-only connectivity (extremely rare as of today).

 "What happened to IPv5?

  Version 5 of the IP family was an experimental protocol developed in
  the 1980s. IPv5 (also called the Internet Stream Protocol) was never
  widely deployed. Since the number 5 was already allocated, this number
  was not considered for the successor to IPv4. Several proposals were
  suggested as the IPv4 successor, and each was assigned a number. In
  the end, it happened that the one with version number 6 was selected."
