Nejlep\u0161\u00ed nab\u00eddku p\u0159edvedl T-Mobile, a\u017e skoro neuv\u011b\u0159itelnou. Bohu\u017eel na\u0161e velk\u00e1 trojka nebere ve\u0159ejnou IPv4 jako samoz\u0159ejmost, ale jako p\u0159\u00edplatkov\u00fd luxus, tedy k tarifu p\u0159ipl\u00e1c\u00edm TM je\u0161t\u011b 99 K\u010d za IPv4 – nap\u0159. O2 m\u00e1 IPv4 za 255 K\u010d – asi se jedn\u00e1 o zlat\u00e9 IP adresy, nev\u00edm. Ka\u017edop\u00e1dn\u011b internet jsem platil v\u017edy fakturou na cel\u00fd rok dop\u0159edu, nyn\u00ed to bude m\u011bs\u00ed\u010dn\u011b. Skoro slzi\u010dka uk\u00e1pne, kdy\u017e jsem za internet po stolet\u00fdch telefonn\u00edch dr\u00e1tech (ale s bondingem) a maxim\u00e1ln\u00ed teoretickou rychlost\u00ed 100\/20 Mbps naposledny platil 5 988 K\u010d.

P\u0159\u00edpojka od spu\u0161t\u011bn\u00ed ani jednou nevyk\u00e1zala jakoukoli chybu a j\u00e1 se dal do p\u0159em\u00fd\u0161len\u00ed jak s takov\u00fdm dom\u00e1c\u00edm optick\u00fdm uzlem co nejv\u00edce pomohu sv\u011btu – samoz\u0159ejm\u011b v r\u00e1mci legality, proto\u017ee s klidnou du\u0161\u00ed mohu \u0159\u00edct, \u017ee i to xDSL s 100\/20 Mbps n\u00e1m bohat\u011b sta\u010dilo, ale ji\u017e jsem poskytovateli PODA zaslal \u017e\u00e1dost o zru\u0161en\u00ed p\u0159\u00edpojky.
