Cobalt RaQ 4 User Manual 41
Overview of virtual sites
The RaQ 4 supports both name-based and IP-based virtual hosting.
The RaQ 4 Administrator sets up the virtual sites, as described in “Adding a
virtual site” on page 47. The following list of information is helpful when
creating a site.
• IP Address To use the RaQ 4, you require an IP address or range of
IP addresses.
• Host name Each virtual site requires a host name (for example, www or ftp).
If the site is connected to the Internet, you must know which IP address the
host name uses.
• Domain name Each virtual site also requires a domain name (for example,
abc.com or xyz.com).
You must also register the domain name. Visit the Internet Corporation for
Assigned Names and Numbers (ICANN) at http://www.icann.org. for a list
of accredited domain-name registrars.
• Web server aliases You can add aliases for Web servers; you are not
restricted to receiving Web requests only on the domain entered in the site
settings.
For the virtual site, enter additional host names or domain names for which
to accept Web requests. For example, enter the aliases domain.com and
www.domain.com.
Separate multiple entries with a comma.
✍
Note: The RaQ 4 supports name-based virtual sites allowing many
sites to share a single IP address. The RaQ 4 Administrator can
create many virtual sites using the same IP address (for example,
192.168.25.77) with a different host name for each site (for
example, both www.abc.com and www.xyz.com can use
192.168.25.77 as their IP address).
✍
Note: The RaQ 4 can serve as the DNS server and provide the host
name.
✍
Note: You must configure the Domain Name System (DNS) records
to resolve the alias addresses in addition to the virtual site name.
