An IP address identifies a network location for internet communication; DNS helps find an address associated with a readable domain name; and a URL identifies a particular web resource. Knowing the difference makes it easier to understand what happens when you open a website.
What is an internet address?
“Internet address” is an everyday umbrella term, not one precise technical label. It may refer to the numeric IP address used in network communication, the readable domain name people recognize, or the URL entered in a browser. These are related, but they are not interchangeable.

ICANN describes the basic choice as reaching someone online by typing “a name or a number.” The number is an IP address; a name can be a domain name. ICANN explains its role and the naming system.
What is an IP address?
An IP address is a network-layer identifier used to direct internet communications. The Internet Assigned Numbers Authority (IANA) defines two versions: IPv4 addresses are 32 bits long, while IPv6 addresses are 128 bits long. IANA’s Number Resources describes both address families.

IP addresses are distributed through a hierarchy rather than assigned by one central service to every device. IANA allocates unallocated address pools to regional internet registries; internet service providers and other registries then participate in distributing addresses to networks and users.
What is the difference between an IP address and a domain name?
An IP address is a numeric network identifier. A domain name is a readable name made of textual labels, such as the name a person types to reach a site. DNS looks up a domain name and finds an associated IP address, so people do not need to memorize numbers. A domain name can help establish an online identity, but it is not itself the website or the network connection.
The relationship is a lookup, not a guarantee that one name permanently points to exactly one machine. The associated address information can be managed, and the available sources describe a domain name as resolving to associated IP addresses rather than defining a permanent one-to-one pairing. ICANN distinguishes domain names from websites and URLs.

DNS, the Domain Name System, is the lookup system that connects a readable domain name with associated IP address information. In simplified form, opening a site follows this sequence:
- You enter a domain name, either directly or as part of a URL.
- Your device uses DNS to look up an IP address associated with that name.
- Your device uses the resulting network address to connect to the internet location.
This is a simplified explanation: the key point is that DNS lets people use names while internet communication uses IP addressing. ICANN describes how a domain name is translated into an IP address.
What is the difference between a URL and a domain name?
A domain name is a readable name used within the internet’s naming system. A URL, or Uniform Resource Locator, is an address for a web resource and may include a domain name. The domain alone does not specify every detail of the resource a browser should open. ICANN states that a domain name is not the same thing as a website or a URL.

IPv4 and IPv6 are two versions of Internet Protocol addressing. They differ in address length and conventional written form; both remain in active use. They are not settings that most users choose independently.
| Version | Address length | Conventional representation | Status |
|---|---|---|---|
| IPv4 | 32 bits | Four decimal octets separated by dots, such as 192.0.2.53 | Still commonly used; initially deployed 1 January 1983, according to IANA |
| IPv6 | 128 bits | Hexadecimal strings separated by colons, such as 2001:0db8:582:ae33::29 | Deployment began in 1999 and IPv6 is active, according to IANA |
The examples illustrate the usual notation; they are not a complete guide to address allocation or every valid formatting rule. The lengths, formats, and deployment dates above are from IANA’s Number Resources.
