Ordinary reverse DNS lookup is available. Do you mean something else?

Eg 1 (using nslookup):
    >nslookup 212.159.99.47 212.159.11.150
    Server: ns-cache1.plus.net
    Address: 212.159.11.150

    Name: line4dd.force9.co.uk
    Address: 212.159.99.47

Eg 2 (using dig):
    $ dig -x 212.159.99.47 212.159.11.150
