Question
A user is unable to reach the website when typing https://www.tudublin.ie in a web browser, but can reach the same site by typing https://52.30.224.143.

Solution
The most likely cause of the issue is DNS (Domain Name System).
Here's why:
-
The Domain Name System (DNS) is responsible for translating domain names (like www.tudublin.ie) into IP addresses (like 52.30.224.143).
-
If a user can access a website by typing in its IP address but not its domain name, it suggests that the DNS is not correctly translating the domain name into the IP address.
-
This could be due to a problem with the user's DNS server, or it could be that the DNS record for the website is not correctly configured.
-
The other options (TCP/IP Protocol Stack, No DHCP address, Invalid IP address on the host, Default Gateway) are less likely because they would typically prevent the user from accessing the website entirely, regardless of whether they typed in the domain name or the IP address.
