Afternic is part of GoDaddy, so I am guessing, if GoDaddy doesn't support .in, then Afternic also does not.
Another question - do .in domains actually sell? I can see many CVCV type listed on Sedo. But then, there is only one CVCV sale on Namebio in 2017. Looks like the only 4Ls with a chance to sell are dictionary 4Ls.
