guideline for name-based web hosting justification

The key to Name based web hosting is using the nameservers
that reside on that host.
Whereas, a host is actually a machine not a www, ftp or pop
or smtp sub-server.
Therein, you are only limited to the number of virtual hosts
by the host (machine's) ability.
Apache uses 500 as a limit however we have over 1000 on one
Linux box that has 4 cpu's
and gig of ram.
This is addressed in BIND VERSION 8.0 and it works.
The inherent name servers do the parsing and it works just
In fact the newer rack mount web servers come ready for
You only need to assign an IP when the customer needs a SSL
or some other IP related
point to point connection. Which usually invokes co-location
and is another matter all together.
The IIS with NT is a IP Hog and we have had disastrous
problems with v-hosting on NT Servers.
We push clients to Unix, Sun and Linux that support
We have had problems with Cold Fusion's database and apps
but, we are working on it.
Of course there will always be an issue that a www site
should have it own IP as this is what the customers expect.
This will be the real challenge to over come.
And here is their reason:
If the dns fails then how do they get their site? On a
v-host named based-you wont get their.
If they have an IP mapped they will get to their site
provide that the host has not failed.
Another, issue that we see is the webhost customers with
alarms on their sites.
So let those Nameservers blink for an update and the phone
ring off of the hook.
Slave to the Machines.......

Oh my god, this has gotta be one of the worst things you
someone to do.
Go and buy all this gear (many thousands of dollars) just so
do the billing you have been doing that costs pennies per
year to do.
It would be cheaper to put each web site on its own server
put each on its own interface card) than to purchase the
hardware needed to do what we already do with current
With PC hardare going for a couple hundred bux, I could put
site on its own server. Sure, I would run out of equipment
someday, but that day isn't for some time.
The days of running out of IP addresses is basically over.
Yes, there is still a crunch, but with IPv6 around the
this issue will be moot in the foreseeable future.
This is an absolutely silly rule that penalizes ANYONE that
actual bandwidth used and not for number of bytes
