I'm not sure I totally understand the question. Subdomains can be 
handled as entirely separate DNS records. You could have a new A record 
for each subdomain pointing to whatever IP address you want, or have the 
subdomains be CNAME records that point to another domain name that has 
an A record for the IP address you want. Does that answer the question?
