Google has always treated subdomains as different sites, separate from the main domain. This is evident within Google Search Console, where subdomains have to be verified separately from the content that exists under the main domain website.
So, if you are using your ISP's DNS service, your ISP will see that. Next, your ISP will then see that you are connecting to the web server at the IP address that subdomain.domain.com points to. Neither your ISP nor your DNS provider will see the entire URL that you are pointing your browser to.

Hijacking of subdomains is often possible against large zone files and these domain names are typically also the ones interesting to attack in the first place because they belong to large enterprises. If you have a security control which relies on DNS, then it's only as secure as your DNS.
One of the disadvantages of opting for a subdomain is that because search engines view them as separate sites, they're treated as separate domains when it comes to determining rankings. Considerations need to be made for developing a subdomain into its own entity.
Subdomains are not private. They can't be made private either. The reason why they can't be is because of DNS, or Domain Name System. Without going into too much detail, DNS is a database of all domains and subdomains, and values associated to them.
A subdomain (new.example.com) will not inherit the domain authority of the existing domain. Google treats a subdomain like a separate domain with separate site authority, even requiring a separate robots.
How do I hide a subdomain from a search engine?
Another way you can remove your subdomain from Google search is via user header x tags – X-Robots-Tag: noindex. This is usually very effective for removing each page in a domain or subdomain. Some webmasters or programmers like this method since it does not alter or change the way you create a page.
Subdomains can be modified as an A record that is pointing to an IP address. Or, they can be modified as a CNAME that is pointing to another domain name. A CNAME record cannot be pointed to an IP address. It is a kind of domain prefix like shop.domainname.com that uses an A record to be pointed to an IP Address.
Because torrenting includes downloading and—if you allow it—simultaneously uploading large amounts of data, your ISP can monitor this unusual spike in bandwidth consumption. From this, the ISP can deduce that you might be torrenting.

It's important to note that you need to create a separate record for each subdomain as subdomains don't inherit the SPF record of their top-level domain.
SPF policies do not automatically get inherited by subdomains. If you use SPF to authenticate your emails and you are sending emails using subdomains, you would need to individually configure SPF records for these subdomains by making modifications to your DNS entries.
How many subdomains is too many?
