Random IP address generatorの使い方
何を計算するか、いつ使うか
Generates random IPv4またはIPv6 addresses個でtest data、examples、documentation. Choose public-looking, privateまたはdocumentation ranges. It uses your browser’s secure random number generator.
使い方の手順
- Choose IPv4またはIPv6.
- Pick the type: public, private, documentationまたはany.
- Set how many addresses you need, up〜200.
- Press “Generate again”個でa new set, then コピー the 結果.
各入力項目の意味
- Version – IPv4またはIPv6.
- Type – Public (routable), private (RFC 1918またはunique local), documentation (TEST-NETまたは2001:db8::/32),またはany.
- 桁数 – 開始 1〜200.
結果の読み方
- Addresses – One address 単位 line, ready〜コピー.
計算式
Each addressはbuilt from random bytes. For public IPv4です、private, loopback, link-local, multicast, reservedのresults、documentation ranges are rejectedとredrawn. Private picks from 10.0.0.0/8、172.16.0.0/12、fc00::/7.の2000::/3, privateの192.168.0.0/16. IPv6 public addresses start
計算例
Five public IPv4 addresses might look like 187.208.201.208と49.150.245.104. They are randomとmay belong〜real networks.
前提と限界
- Random public addresses may belong〜real organisations. Do not scanまたはcontact them.
- For documentation、use the documentation type, whichはreservedです個でexamples、never routed.
よくある間違い
- a real test against live systems.のUsing random public addresses
- Putting random addresses into a firewall ruleまたはallow list.
- Expecting the same list after pressing the button again.
よくある質問
Are the addresses real?
They are random, so some will belong〜real networks. They are not tied〜any deviceまたはperson.
Which addresses are safe個でexamples?
Use the documentation ranges: 192.0.2.0/24、198.51.100.0/24, 203.0.113.0/24、2001:db8::/32.
Is the generator truly random?
It uses the browser’s cryptographic random source.
缶 I generate private addresses?
はい. Choose the private type.
