unc – simulates a CNAME removal of DNS on the local machine

My company will delete a CNAME record from DNS and replace it with a new record "\ OLDCNAME Apps" in "\ NEWCNAME Apps". Currently, both values ​​exist on the network and both refer to the same set of files and folders. We're currently trying to update configuration files (.properties, .ini, .xml) that have references to OLDCNAME to use the new CNAME and test the applications to see if they are working properly.

Is there a way to simulate the deletion of OLDCNAME on a local machine so that we can test the applications before the company deletes the old CNAME record from the DNS?

Many Thanks

cdn – How do I register a custom domain in Azure if I can not add the Azure Web App host name as a CNAME to our domain?

Let's say we run a website greatwebsite.com, This is a multilingual website we use / de, / de, / fr as path prefixes for handling languages ​​(rather than top-level domains).

We use a CDN to open the entire site, and greatwebsite.com is CNAME too greatcdnprovider.com It then receives dynamic content from the configured origin.

We are in the process of launching a new version of this website and we would like to do this per language. We start with a small segment (language). The new website is running on Azure.

Our CDN can use different origins based on the request path. We want to send all requests first greatwebsite.com/[insert-language-here] in the new Azure web application, while all other languages ​​are displayed on the current Web site.

Now we can not add a CNAME or A record greatwebsite.combecause we already gave it to CNAME greatcdnprovider.com,

What will we do during this transition?

One idea is to create a subdomain azure.greatwebsite.com and CNAME you to the Azure web application. Then we have the CDN that we can use azure.greatwebsite.com as it originated for inquiriesgreatwebsite.com/de,

So, greatwebsite.com gets CNAME too greatcdnprovided.com then use azure.greatwebsite.com which in turn is CNAME or contains an A record to our Azure web app.

Does this sound the right way or do we have other options?

Dynamic subdomains – Should I use DNS API or wildcard CNAME record?

I want to deploy new subdomains based on user requests. I realized that there are two ways to do this:

  1. Use the DNS provider API to register new CNAME records that point to pages within the site
  2. Make placeholder * .example.com CNAME, note down these points example.com/subrouter which determines which domain it is called from, and returns related documents (or tons of virtual hosts on Apache).

Method 1 feels a lot more natural, because I stick to the original design. Method 2 is flexible and does the job.

Server management is not my primary field, so hopefully that will sort out for me. Is there a reason to choose one method over the other, in terms of performance, scalability or security? Which method is preferred by professionals?

cname – How do I create a Google site and use it with a Google domain?

How can I create a Google site and use it with a Google domain?

I have registered a domain through Google Domains (let's call it) example.com). I then created a google site (we call it sites.google.com/site/example123)

Now I try to show example.com to this address.

To do this, I've added a CNAME listing in Google Domains, but if I understand it, I'll have to configure that as well Website URL on Google Sites.

But when I enter www.example.com or example.com there it tells me

This location is already in use by another service. Please select another one.

Without further explanation or instructions. Googling was not much help – I found some forum news from 7 years ago that complained about it.

Domain Name System – Registrar CNAME for forwarding the hosted zone to ephemeral ELBs

I have a domain "blabla.com" with a registrar. I have a bunch of ELBs to handle the traffic, but their domain names are constantly changing.

I would like to route the blabla.com traffic from AWS route53 to the ELBs to benefit from advanced routing (weighted routing, etc.).

Is there a way to set this up?

I created a hosted zone for blabla.com in route53. I thought about creating a CNAME from the registrar. I can not refer to the ELBs because they do not have a fixed domain name. Somehow, I need a way to say "redirect everything to AWS" so AWS uses my route53 rules to redirect traffic.

Any idea how to achieve this?

apache 2.2 – CNAME to the external virtualhost subdomain that does not lead to the desired page

Recently, a friend and I played around with the DNS settings on our sites, and out of curiosity a CNAME for a subdomain (let's call it test.a.com) pointing to a subdomain on my domain (test.b.com) ). While name resolution works, the resulting webpage is my Flask application (app.b.com). This is neither the page pointed to by the CNAME record nor the main domain (b.com). We checked the HTTP request and found that the host header was its subdomain (test.a.com). I understand why he did not get to the right subdomain, but is there a way for it to work? I feel like it's not like that, but I just wanted to make sure. Many Thanks!

Tools that serve as a reference:

Bind9 for DNS, Apache2 for webserver

Edit: Also an additional question – an idea why the Flask application is used by default?
