For IPv6 I consider it "address spam".  My content filter will give you some extra tiny score if your MX uses such an address.

If you want to do it, make sure you do understand the restrictions that apply to IPv6 addresses, like U/G bits, etc.  Too many people unfortunately just think it's cool in a weird geeky sense and violate RFCs with them.  I was very close to write an article about that after W6D...

         Stop bit received. Insert coin for new address family.
