ASN lookup का उपयोग कैसे करें
यह क्या गणना करता है और कब उपयोग करें
the network that announces an IP address के Finds the autonomous system number (ASN), or the holder और an AS number you already know. An ASN identifies one network on the internet, such as a provider, a cloud company या a university. के announced address ranges
उपयोग कैसे करें, चरण दर चरण
- Enter an IP address, या an AS संख्या such as AS15169.
- Press “Look up ASN”.
- Read the AS संख्या, holder और whether it है global routing. में visible
- announced prefixes undernea-वाँ. के Check the list
हर इनपुट का मतलब
- IP address या AS संख्या – An IPv4 या IPv6 address, या an AS number wi-वाँ या without the “AS” prefix.
परिणाम कैसे पढ़ें
- AS संख्या और holder – The network’s संख्या और the organisation that holds it.
- Announced – Whether the नेटवर्क है the global routing table. में currently visible
- Prefixes announced – IPv4 के The count और them. के IPv6 address ranges the network advertises, with a sample
सूत्र
नहीं calculation. Networks use the BGP protocol से announce which address ranges (prefixes) they कैन reach, प्रति वस्तु under an AS संख्या. RIPEstat reads these announcements से routing collectors around the world.
एक हल किया उदाहरण
Looking up 8.8.8.8 returns AS15169, held by Google LLC, which announces 8.8.8.0/24 among many other ranges.
मान्यताएँ और सीमाएँ
- डेटा comes से RIPEstat और is requested when you press the button.
- a long prefix list के Only the first part है shown.
- An address that nobody announces cannot be mapped से a नेटवर्क.
आम गलतियाँ
- Entering an AS संख्या with a typo या extra text, such as “AS 15169 Google”.
- Assuming one organisation has one ASN. Large companies often operate several.
- Reading the ASN as a location. It identifies a नेटवर्क, which कैन span many countries.
