What does the “www2″ in web address? [internet address] [www2]
Q: For example, this link below.
http: / / www2.packetstorm.org: 443 /

yes correct.
www(2..n) is usually used to note that server is mirror of main www.
Actually, more commonly it is load-balancing webservers.
Re:it is all semantics. dont worry about it.
it couldbe bobsmachine.yahoo.com. don't matter.
Re:always use one and only one A record for a host and that should be the true host name of the machine.
Everythingelse should be a CNAME.
But like everyone's said. Its just a name.

Actually the webserver name is TKxxxxxxxx or something similar (MS has a really mangled machine naming convention that you don't really want to know about) The DNS entry is totally unconnected to the physical server name. DNS entry is a map of a name to an IP address.
So I could register in the DNS foo.microsoft.com and bar.microsoft.com and point both of them at the same IP for example. Why would I do this? Well I could host two different websites on the same machine then use host headers to differentiate between the requests.
In this case the support.microsoft.com's DNS record points to a virtual IP address in Akamai edge-network. This maps your request to one of Akamai's servers nearest you.
what he said applies a host record or A record can be name.ip.co.uk then you could have either multiple A records pointing to that address or CNAMES which map names to names ie name2.ip.co.uk maps to name.ip.co.uk.
it does of course get a bit deeper than that but hose basics should see you well on your way

Re:ohhhhh… that makes sense. www2 is the cname for the webserver
ok, so a webserver can take any name???
ie) "http://support.microsoft.com" (http://support.microsoft.com") , the webserver name is "support"?? rather than the more common "www"?? correct?
Re:its a host address in the domain packetstorm.org is the name of the domain. the www2 before it is simply a host record in the packetstorm.org domain.
DNS names work from right to left host being the right most entry. eg
www.www2.packetstorm.org
would be a www. host in the www2 subdomain of the packetstorm.org parent domain. the hosts can be anything www. etc is simply for clarity sakes as most people will always look for a www. in a domain name.
does this help?
