Pane mitezo yakawanda inodzorerwa asi iyo yose ine minda imwechete iyo inotevera:
- Zita guru revhareji
- Mutungamiri wechipatara
- A timestamp inoshanduka kana domain racho richivandudzwa
- Nhamba yemasekondi pamberi pezvese inofanira kuvandudzwa
- Nhamba yemasekondi musati wabudirira kuburitswa inofanira kudzoka zvakare
- Iko kumucheto kwepamusoro mumasekondi masere nzvimbo isati yaonekwa seine kodzero
- Izvozvo zvinokonzerwa neTTL.
Iyi peji yepawebhu inopa mahedheni akanaka pamusoro pe SOA.
Summary
Pane zviri pachena kuti dzimwe dzakawanda shanduko dzakadaro -i dzinopa rondedzero uye -T inotsvaga kushandisa TCP / IP pane UDP.
Iwe uchaona kuti ma web server akawanda acharamba marudzi aya emubvunzo.
Muzhinji iwe unogona kunge uchingofanira kushandisa mutemo wekutumira kudzorera kana iri IP yezita rezita redaire kana zita rekuda kwekero ye IP.
