“canon” and “canonical” have always been difficult words for me.
I asked: In this sentence "In case of a content discrepancy between English and the translation, the English version is canonical." what does canonical mean?
It replied with reference URLs, which didn’t make it into the below:
In the context of the sentence "In case of a content discrepancy between English and the translation
, the English version is canonical", "canonical" means authoritative or official. It implies that the English version is the standard against which any other translations or versions should be compared or judged, and is considered the authoritative or official version in case of any discrepancies or differences.
Then, I asked: Explain the difference between CNAME and A records in DNS
A CNAME (Canonical Name) record is used in the Domain Name System (DNS) to create an alias from one domain name to another
. When a DNS lookup is performed for the alias name, it returns the canonical name, which points to another DNS record, such as an A record that contains the IP address of the server hosting the website.
An A record is a DNS record that maps a domain or subdomain to an IPv4 address. It is the standard DNS record type and is used to resolve a domain name to its corresponding IP address. When a DNS lookup is performed for a domain name, the A record is queried to obtain the IP address of the web server that hosts the website.
The main difference between CNAME and A records is that a CNAME record points to another domain name, while an A record points directly to an IP address. It is generally recommended to use A records when possible, as they have fewer performance concerns and are typically easier to manage than CNAME records. However, CNAME records can be useful if you want to create an alias for a domain that may change its IP address frequently, or if you want to create subdomains for specific purposes, such as hosting a separate mail server.
