# Domains, DNS, oh no
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
### Hello Class of CS4116
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
So we use domains every day, even if ye dont know it
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
52.30.181.100
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
52.30.181.100 - Brightspace
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
209.85.203.94
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
209.85.203.94 - Google
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Those numbers arent very human friendly
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
So what is teh solution?
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
## Getting a domain!
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
There are many domain hosts to go for
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
And prices range from €1/year to €infinity/year
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
* .ie
|
|
* .com
|
|
* .tk
|
|
* .coffee
|
|
* .eu
|
|
* .me
|
|
* .gay
|
|
* ...
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
There is even .cat, though that is off limits to most of us.....
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
I recommend using <<https://www.blacknight.com/>> for .ie
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
And <<https://www.namecheap.com/>> for everything else
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
I am going to focus on .ie
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
These will set ye back ~€7 for the first year.
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Then €30 for every year afterwards
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Enter your perfect domain name into the big box
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
It will then show ye a list of options
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Select one, add it to the cart
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
In the config select ``I'm hosting my website somewhere else``
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Then add these two as nameservers:
|
|
* ``nadia.ns.cloudflare.com``
|
|
* ``neil.ns.cloudflare.com``
|
|
|
|
|
|
Press ``Update`` then ``Checkout`` for payment
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
You will verify that ye have a connection to Ireland
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Your Student ID will work for this
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Couldnt find a name that suited you in ASCII text?
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Have no fear!
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
## Punycode to the rescue!
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Say you want ``brendán.ie``
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
But because of the ``á`` it is not a "normal" domain.
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Go to <<https://www.punycoder.com/>> and enter in your special domain
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Boom: ``xn--brendn-tta.ie``
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Or say ye wanted to go wild and have an Ogham domain name?
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
``ᚁᚏᚓᚅᚇᚐᚅ.com`` for example (brendan in Ogham)
|
|
|

|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
``ᚁᚏᚓᚅᚇᚐᚅ.com`` becomes ``xn--7ueiah2bis.com``
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Magic!
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
And congrats! You now have a domain.
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
As we saw in the earlier slides a domain points to an IP address.
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Ye can point your domain to another domain.
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
These go to the same location
|
|
* <<https://brendan.ie>>
|
|
* <<https://brendan.coffee>>
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
So anyone in CS4116 would love to point
|
|
<<https://hi-conor-ryan-give-me-a1.ie>>
|
|
To their InfinityFree instance
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
## For that we need DNS
|
|
|
|
InfinityFree has their own [(good) docs][1] for this.
|
|
But I prefer to use [CNAME for this][2]
|
|
|
|

|
|
[2]: https://forum.infinityfree.com/docs?topic=87420
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Cloudflare is one of teh best DNS providers
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
<<https://cloudflare.com>>
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Signup, you should know how to do this.....
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
On teh homepage select ``Add a site``
|
|
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Enter in your domain (``hi-conor-ryan-give-me-a1.ie``)
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Will take little while for it to be activated.
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
So go make a cuppa.
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
If ye are using InfinityFree checkout their [CNAME docs][2]
|
|
|
|
-------------------------------------------------------------------------
|
|
|
|
Thats kinda the end of this, it is targeted to CS4116. |
