AWS should not take capital letters in DNS URL

Question

Why is AWS ELB field designed to allow capital letters ?
The global truth is that DNS in browser always is parsed as lowercase letters . When using them as PUBLIC IP in applications, we must parse it as lowercase as well although AWS Load Balancer field allows capital letters. Then why allow capital letters at all ? Should not this be an improvement on AWS side ?

Answer

Hello,

The use of capital letters in ELB fields for DNS URLs is mainly about compatibility. It’s about adhering to different DNS standards and allowing for potential instances where uppercase letters might be used in DNS names such as legacy systems or applications. Allowing capital letters provides the necessary flexibility for naming conventions and ensures compatibility with applications and infrastructure.
