We strongly discourage use of IP address space for virtual hosting
services because this represents no technical reason to assign more than
one address to a host. Therefore it is in conflict with address space
conservation.
We recommend to use URLs of the form
http://www.www-provider.com/customer1/
http://www.www-provider.com/customer2/
or if customers desire www.customer.com:
http://www.customer1.com/customer1/
http://www.customer2.com/customer2/
with CNAME RRs for www.customer1.com and www.customer2.com pointing to
the real server. The latter variant provides mobility for the customer
without using extra address space.
If you have any further questions, please do not hesitate to contact us.
