Can someone explain to me why this is a valid URL?

  >A domain is a non-empty ASCII string that identifies a realm within a network. [RFC1034][1] >The example.com and example.com. domains are not equivalent and typically treated as distinct.[1] When a user needs to type a domain name, the length of each label is omitted and the labels are separated by dots ("."). Since a complete domain name ends with the root label, this leads to a printed form which ends in a dot. We use this property to distinguish between: - a character string which represents a complete domain name (often called "absolute"). For example, "poneria.ISI.EDU." - a character string that represents the starting labels of a domain name which is incomplete, and should be completed by local software using knowledge of the local domain (often called "relative"). For example, "poneria" used in the ISI.EDU domain. Relative names are either taken relative to a well known origin, or to a list of domains used as a search list. Relative names appear mostly at the user interface, where their interpretation varies from implementation to implementation, and in master files, where they are relative to a single origin domain name. The most common interpretation uses the root "." as either the single origin or as one of the members of the search list, so a multi-label relative name is often one where the trailing dot has been omitted to save typing.[2] [1] https://url.spec.whatwg.org/#concept-domain https://url.spec.whatwg.org/#concept-domain [2] https://www.rfc-editor.org/rfc/rfc1034 https://www.rfc-editor.org/rfc/rfc1034
