How to do your own level two domain name (the third) (turn)

I have seen this forum there is a netizen is intended to do a free two domain name services, the pan-domain name and procedures have been got, excitedly rented the virtual host space, only to find that because of the host problem, simply do not.
Therefore, it is very important to choose the right space.
After I finished (bis), there is a netizen in this forum for me to put some doubt, one of them is, have a pan domain name, but also have a stand-alone host just line, because this has independent IP, virtual host don't think. Oh, I do not have so much money to rent a stand-alone IP host, I rented is a virtual host, that IP has hundreds of domain names, but also made a name.netmiss.net this two-level domain name.
Let me separate, in a way, there is an independent IP host is undoubtedly the best choice, so that netmiss.net or any xxx.netmiss.net all point to this IP, that is to point to your home index.cgi or Index.php and so on, the program can work, so that's the best way. Strongly recommend conditional or rich netizens adopt this way (at the same time strongly requested the space to give me some, rich money to give me some, hehe).
When you have to face the reality of no money, the virtual host is the way that must be used. In the areas of universal domain names, programs, and hosts, it takes most of my time and effort to find the right virtual host. Almost to the host I know sent a letter asked, every day in the K666 forum, see advertising asked him if he has to meet my requirements of the space, is at that time in the mixed-cooked, hehe.
At first, I almost disappointed, some space business told me that there is no such space, and some told me that although there is no, but he has a very good lake space Oh, really laugh and cry, I want to lake space to do what?
Well, to put it simply, what are the conditions to meet?
1, the pan-domain name resolution, this and (one) said the resolution is not the same, because an IP may have a lot of virtual host users, so the host also has an analytic process, the access to this IP according to the different domain name resolution to the corresponding directory, When all xxx.netmiss.net of the DNS party point to the IP of this host, the host Party will point them all to a directory.
2, the default home page can be index.cgi or index.php or index.asp or index.shtml, so as to directly point to the program. Of course, do not meet this condition can also be done, but to sacrifice some function, do not you want to strive for perfection?
Well, these are the two articles.
Most of the current virtual hosts are 3: UNIX, LINUX, and Win2000 (or NT).
First look at 2000, the front of the rental host found not to use the Netizen, is because the rental is 2000, the host told him, can not bind *.domain.com, only one binding, it is not a generic domain name, and the host will not give him too much binding, when he went to the forum to ask, Since then I did not know very well, not very confident, so did not help him answer, and then no one answered him. So, 2000 is not good, this may be very few ASP's level two domain name program reason.
