Does each e.g. wordpress subdomain have a unique IP? - wordpress

Webhosting sites like wordpress or godaddy have several subdomains like https://hello.wordpress.com/ . Does each of them have a unique IP-address (v4 or v6)? If not, how does routing work?
I just checked and the output from host hello.wordpress.com equals host www.wordpress.com. So I assume that...
www.wordpress.com resolves to e.g. 192.0.78.12/ and
hello.wordpress.com resolves to e.g. 192.0.78.12/hello or similar.
Is this assumption correct?

You have an A record for each subdomain, so you can point it to the same IP address or a different one.
The routing of the sites is just done with the server configuration, I can't speak for GoDaddy or WordPress as I don't know what stack they are using.
I believe a standard Apache server would have the main domain in /public_html and the subdomain in a /sub.domain.com folder.

How to host the main domain and subdomains at 2 different hosting sites from godaddy?

I have bought the domain from godaddy.
And I have designed the UI which is the main site hosted at say webflow or wordpress.
Now I want to host the dashboard of the main site to the subdomain of this main site from heroku.
How to achieve that?
Domain bought: goDaddy
main site: abcd.com
sub domain: dashboard.abcd.com
main site hosted at: wordpress
sub domain hosted at: abcd.herokuapp.com
Now I want to change the subdomain abcd.herokuapp.com to dashboard.abcd.com
I tried creating an 'A' record at goDaddy DNS settings for dashboard.abcd.com but it wants me to enter an IP address of heroku but when I created a DNS Zone in Heroku for dashboard.abcd.com, it doesn't seem to provide an IP address. It only provides the DNS Target value.
I laso tried to put the abcd.herokuapp.com in Goddaddy dns settings in Points To field but it doen't accpets it. It requires an IP address.
Heroku uses dynamic IP address for the dynos so it’s impossible for Heroku to provide an IP address instead it provides a DNS target. Unfortunately GoDaddy doesn’t support ALIAS/ANAME records. You might want to check out other DNS providers who support ALIAS/ANAME out of the box to configure the APEX domain.

Hosting subdomain without a name domain nginx

I want to add a subdomain to my server. I do have have an ip address given by the hosting server but I don't have the name domain yet. Is it possible to host like:
subdomain.152.235.235.85 <-- I tried this by Is not working for me, perhaps this is not possible
Or is there a better way to have subdomain without having a name domain yet?
If you want use this site for few devices, you can add to file hosts your domain: 152.235.235.85 subdomain.test.site
But just add subdomain to IP is impossible.

Separate Domain Registrar and Host, possible to use CDN?

I am just wondering if this is possible/how I could go about doing this.
I work for a company that has their domain name registered on Site A while their hosting is on Site B. This is no issue as we just have the Registrar at Site A point the Name Servers to Site B. Easy.
Where I get a little confused, is say I would like to use a CDN such as CloudFlare (Site C), typically in a basic case, I would go to the registrar/host and just change my Name Servers to the ones given by CloudFlare. However if my Registrar and Domain Host are different, it appears someone could get lost in the mix, as if I go from Site A point to Site C .. how does host at Site B supply Site C with all the information to host and control the CDN for?
Thanks for the insight!
I reached out to CloudFlare and got this very simple, perfect answer.
Here's how it will work for you :
At your domain registrar, you will set your authoritative name servers to the ones that CloudFlare will assign to you when you sign up.
Within CloudFlare, using our dashboard, you will configure your DNS zone file to point your domain to the IP address of the server assigned to you by your hosting provider.
The CloudFlare reverse proxy does the rest!
Hope this helps!

DNS and Subdomain IIS

I have 2 web apps installed on my IIS, one running as app1.mydomain and other one as app2.mydomain
In the test environment I just copied about two entries pointed to 127.0.0.1
What changes do I have to do in order to put this on production server, I mean on DNS level?
Can I use URL re-write on IIS to avoid changes for DNS?
Thanks
You need to add A or CNAME records mapping both subdomains to the external IP address of your server.
This tells web browsers to go to your server when you go to the subdomain; URL rewriting has nothing to do with this.

How to set up subdomains on IIS 7

I have a website sitting on an IIS 7 server:
WWW.example.COM
I would like to create several sub domains that looks like
SUBDOMAIN1.example.COM
I created an IIS website and I set the bindings to be
http, port 80, the ip address of my server, and SUBDOMAIN1.example.COM and the physical path to a folder under example.COM
I restarted my website and clicked on browse, the browser than opened with the address:
http://SUBDOMAIN1.example.COM
But the website doesn't show up.
Do I have to do something with the DNS?
This one drove me crazy... basically you need two things:
1) Make sure your DNS is setup to point to your subdomain. This means to make sure you have an A Record in the DNS for your subdomain and point to the same IP.
2) You must add an additional website in IIS 7 named subdomain.example.com
Sites > Add Website
Site Name: subdomain.example.com
Physical Path: select the subdomain directory
Binding: same ip as example.com
Host name: subdomain.example.com
Wildcard method: Add the following entry into your DNS server and change the domain and IP address accordingly.
*.example.com IN A 1.2.3.4
http://www.webmasterworld.com/microsoft_asp_net/3194877.htm
If your computer can't find the IP address associated with SUBDOMAIN1.example.COM, it will not find the site.
You need to either change your hosts file (so you can at least test things - this will be a local change, only available to yourself), or update DNS so the name will resolve correctly (so the rest of the world can see it).
As DotNetMensch said but you DO NOT need to add another site in IIS as this can also cause further problems and make things more complicated because you then have a website within a website so the file paths, masterpage paths and web.config paths may need changing. You just need to edit teh bindings of the existing site and add the new subdomain there.
So:
Add sub-domain to DNS records. My host (RackSpace) uses a web portal to do this so you just log in and go to Network->Domains(DNS)->Actions->Create Zone, and enter your subdomain as mysubdomain.domain.com etc, leave the other settings as default
Go to your domain in IIS, right-click->Edit Bindings->Add, and add your new subdomain leaving everything else the same e.g. mysubdomain.domain.com
You may need to wait 5-10 mins for the DNS records to update but that's all you need.
