you mean "generic"? well, if you have a /16 network, will you select names one by one? some providers play games here and use a dictionary: $ host 93.74.0.105 105.0.74.93.in-addr.arpa domain name pointer latheness-pair.volia.net. $ host 93.74.0.106 106.0.74.93.in-addr.arpa domain name pointer practical-sheriff.volia.net. ... I find this practice "worst".
