[Bug 1808730] Re: Why instance hostnames are not case sensitive
By the RFC952 [1] the hostname is case-insensitive: "No distinction is
made between upper and lower case."
By the RCF4343 the DNS lookups are also case insensitives [2]:
"According to the original DNS design decision, comparisons on name
lookup for DNS queries should be case insensitive"

Title:
Why instance hostnames are not case sensitive
Status in OpenStack Compute (nova):
Invalid
Bug description:
I create some instances in R.I find these instances` hostnames are not
sensitive.
eg, The name I input is TEST,but login the instance,the hostname is
test.
I study the code of creating instances, but I find a function named sanitized_hostname.
In this function,it will call the function hostname.lower().But I do not know why do like this.
Can somebody help me explain this problem?
