<\/div>\n

Adresa WAN (wide area network) je adresa, kter\u00e1 je p\u0159i\u0159azena za\u0159\u00edzen\u00ed, kter\u00e9 se nach\u00e1z\u00ed v rozs\u00e1hl\u00e9 s\u00edti. Tento typ adresy se pou\u017e\u00edv\u00e1 k identifikaci konkr\u00e9tn\u00edho za\u0159\u00edzen\u00ed v s\u00edti, co\u017e umo\u017e\u0148uje sm\u011brov\u00e1n\u00ed dat k tomuto za\u0159\u00edzen\u00ed. Adresy WAN obvykle p\u0159id\u011bluje poskytovatel internetov\u00fdch slu\u017eeb (ISP) nebo sm\u011brova\u010d \u010di p\u0159ep\u00edna\u010d. Obvykle jsou p\u0159id\u011blov\u00e1ny v hierarchick\u00e9m form\u00e1tu a slou\u017e\u00ed k identifikaci zem\u011bpisn\u00e9 polohy za\u0159\u00edzen\u00ed. <\/p>\n
