I'm not sure what that means. No, seriously, my dictionary says "study or science of the meaning of language forms", but does that include the meaning of single words or only about the meaning imparted by sentence structure, or something else? Of course this is about the meaning of words. Specifically, about the meanings of "domain" and "hostname" (in the context of DNS), keeping in mind that many key words in our industry have no well-agreed-upon single definition for all purposes and these are likely to be among them. "Domain" means something like "a set of nodes in the DNS tree structure", where nodes have associated info about hosts and domains. "Hostname" sometimes seems to mean the string returned by the "hostname" command/function (being distinguished from hostname aliases), but I think it's fair in the DNS context to use "a domain name which has an assigned IP". (In the DNS, "host" doesn't mean "computer", of course. Hosts are whatever have assigned IP addresses, except maybe networks. Does DNS even know about networks? I can't think why it should.) > Let's say you have a host with IP address 1.2.3.4, and a name > "fubar.org" (A RR) that resolves to 1.2.3.4. Is "fubar.org" a domain > or a hostname?

They are all domain names and, except for "fubar.org", hostnames. (No host, no hostname.) > Let's say you have names "fubar.org", "alpha.fubar.org", and > "beta.fubar.org".
