HTML5 input type=number and decimals/floats

if you want all the numbers to be valid, integers and decimals alike? In this case, set step to “any”
if you only want to accept positive numbers, you’ll want to add min=”0″.

<input type="number" step="any" />
<input type="number" min="0" />

DNS (Domain Name System)

DNS, which stands for domain name system, controls your domain name’s website and email settings. When visitors go to your domain name, its DNS settings control which company’s server it reaches out to. For example, if you use GoDaddy’s DNS settings, visitors will reach GoDaddy’s servers when using your domain name.

Difference between host name and domain name

  • hostname is the name given to the end-point (the machine in question)
    • and will be used to identify it over DNS if that is configured
  • domain is the name given to the ‘network
    • it will be required to reach the network from an external point (like the Internet)

It is usually written in the form, — for example

If you are in (say) a college campus named called ‘The-University‘,
and its domain is called ‘‘,
a machine on the campus network called ‘mymachine‘ would be addressed as, ‘‘.

If you were trying to connect to this machine from your home network,
you would address it with that full name.
The domain part would reach you to the campus network
and the hostname would let you reach the exact machine in the campus.
I am avoiding the details of IP Addressing and gateways here.

For this reason, while accessing the machine from another machine within the campus
may work with just the hostname (mymachine) without the use of the domain name.

To taken an analogy, if you are in the same city, the street name suffices.
But, to address a place in another city, you would usually add the city name after the street.
