to determine  primary DNS server:

whois -h whois.networksolutions.com domainname.com (Only works for .com 
.net and .org domains)
or:
nslookup -q=NS domainname.com
or:
dig domainname.com


To determine who hosts the domain is harder.
You can traceroute to it (Which should at least give you the upstream 
ISP) or you can do a whois against the IP like:
whois -h whois.arin.net ip.ip.ip.ip 
substitute RIPE or APNIC's whois servers for whois.arin.net when dealing 
with non-North American IP's.
This wil also give you the upstream ISP usually.
