No organisation is registered under the name "tcsa.com.ar"
The addresses above are where it actually runs — resolved live and attributed to the operator that registered each range. That is the answer for a domain; a name match here would only add something if a company were registered under this name too.
Sites hosted on a provider (OVH, Cloudflare, AWS and the like) show that provider, because the address space is registered to them rather than to the site's owner.
