Bulk Resolution of IP Address - Script?

I have a list of IP addresses within a comma delimited CSV file. They are all located within column A. (ip.csv) I would like to use WHOIS, or if there is a better way please advise to check each of these IP addresses and then output the details to a new csv file (resolved.csv). This will need a column per descriptor in the WHOIS record, such as inetnum, netname, descr, country... Ultimately I am looking to parse the results to some form of useful data. Having installed WHOIS the whois 86.63.229.33 works great but this is complicated for new user. Merci
