Speaking of ccTLD second level public suffixes, for .in I've just
noticed not only some "expected" suffixes like:

    ac.in biz.in co.in com.in edu.in firm.in gen.in gov.in ind.in
    info.in net.in nic.in org.in res.in web.in

But also some that appear to just mirror other ccTLDs without an obvious
connection to a category of child domains (com, edu, gov, net, org, ...):

    ai.in am.in ca.in cn.in er.in io.in me.in pg.in tv.in uk.in us.in

What are these for?  I'm afraid  these may create or add to user confusion.
