What is the minimum number of sub domain’s )?
3 Answers. RFC 1034 section 3.1 specifies that labels (parts of DNS names) can be from 0 to 63 octets long, and the zero-length one is reserved for the root zone only. So in practice, the limits are 1 to 63 characters.
Can a subdomain be all numbers?
Technically William is right, and only letters, numbers and hyphen (-) are allowed in subdomains. However: in practice, you will see that underscore (_) will also work in all major browsers, but this is not guaranteed. Some providers and other services may not allow you to set it in DNS.
Can URL start with a number?

Which is an example of a subdomain name?
Names and maximum lengths of the parts of a URL. A subdomain is a domain that is part of a larger domain; the only domain that is not also a subdomain is the root domain. For example, west.example.com and east.example.com are subdomains of the example.com domain, which in turn is a subdomain of the com top-level domain (TLD).
What’s the maximum length of a domain name?
In theory this subdivision can go down to 127 levels deep, and each DNS label can contain up to 63 characters, as long as the whole domain name does not exceed a total length of 255 characters. But in practice most domain registries limit at 253 characters. share|improve this answer. edited Jan 1 ’16 at 16:21.
