Why does the following nslookup not work given:
WHOIS shows:
Domain Name: CS.COM
Domain servers:
dns-01.ns.cs.com 152.163.159.235
dns-02.ns.cs.com 205.188.157.235
% host dns-01.ns.cs.com
dns-01.ns.cs.com has address 152.163.159.235
% host 152.163.159.235
235.159.163.152.IN-ADDR.ARPA domain name pointer dns-01.ns.cs.com
% nslookup cs.com dns-01.ns.cs.com
