  1. the I P address and the DNS
  2. let's start saying that a protocol is a
  3. well known set of rules for machines to communicate
  4. the I P address. We already heard the words I P
  5. I P address is just a bunch of numbers that are composed of course by bits.
  6. And it's unique for each device is
  7. it consists in asking from your computer to another
  8. computer for an information or a message of course,
  9. as always.
  10. Um
  11. so your computer sends um this this I.
  12. P address and the origin address to the other computer.
  13. So the other computers knows where to respond
  14. and where to send the information.
  15. V I P V four that before was designed in 90 73
  16. was used for the first time between the eighties I would say.
  17. And provided more than four billions of I. P address unique all around the world.
  18. Instead the IPV six. It's much newer version, new version
  19. And in this composed of 128 bits
  20. and provides 340 under civilian unique addresses.
  21. DNS
  22. DNS consists in the main network system and associates
  23. the name vu vu vu dot example dot com.
  24. For example, with the corresponding address
  25. the computer uses the DNS to search the domain names and the associated
  26. iP addresses.
  27. Of course,
  28. it's impossible for one IP address to control all
  29. of the eight billion devices connected around the world.
  30. So there are different reasons divided and located hot hierarchy, um,
  31. that are responsible for a major domain for example
  32. dot com
  33. dot org
  34. dot net dot
  35. and etcetera
  36. DNS. Spoofing.
  37. DNS proofing means that when an actor acts your DNS and change its i p address
  38. here, for example, we can see
  39. The IPV four vs IPV six really quickly.
