DNS resolution steps
- Enter domain name in internet browser
- Computer will then send domain name
- Name sent is in DNS request form
- You get domain on ISP or on your internet services provider

- In case it does not happen then ISP will forward this request to other providers
- When there is correct result then IP address of domain comes to user
- Therefore computer of user is able to communicate with server
