what others DNS available?

What are the other options we have other than DNS we use?
thanks

Not sure what you're asking. The alternative to buying a domain is getting a free subdomain. I recommend the following:

If you want to buy a domain, the alternative to hosting your own dns server is going for a free domain hosting service elsewhere. Here's a comparison chart I've cooked up:

oh thanks anyway for the sites address...what i mean is other than DNS what else can we use? ...or DNS the only choice that we have?

by the way do you know how many domain names we can create today if we own the internet? the maximum of the domain names i mean....thank you very much...i appreciate your help

On a private network the alternative to DNS is called WINS. There is no public technology that is an alternative to DNS.

"the maximum of the domain names i mean"

You seem to be full of insane questions. But I will humor you.

The short answer:

over 0.000000003 google domains (a google is a 1 followed by 100 zeros)

The long answer:

A domain name cannot be longer than 254 characters. A domain name can contain periods, dashes, letters (case insensitive), and numbers. In my calculation I will exclude non-ascii letters which seems to be the newest extension to the DNS (foreign characters in domain names). So that makes for 26 letters + 10 digits + 2 extra characters = 38 characters.

254 to the power of 38 = 2.4192526840802981174698167436685e+91

In translation, that is:

~24192526840802981174698167436685000000000000000000000000000000000000000000000000000000000000 domains.

This is an approximation. Since the number is so huge, and my calculator does not have enough space to display such a large number, a lot of the value is lost. So the number is actually bigger than that. Also, since I did not include the newly supported foreign characters in domain names, that substantially increases the number above. Also domains cannot start or end with a period or dash. This decreases the number by a relatively small amount.

geez...alright...that wasnt my question...its a questions for my assignment project ...hehe

but thanks anyway
