Overview

Every device on the Internet has an Internet Protocol address (IP address), which is a unique number issued to it. This article briefly explains what IP addresses are and how to manage them at GreggHost.

What are IP addresses? What exactly do they do?

An IP address, like a phone number or a street address, identifies networked devices and specifies their location on a network such as the Internet. There are two different IP address variations available right now.

IPv4 is an older protocol with a limited number of devices that it can support.

IPv6 — A newer alternative that supports many more devices and has been widely embraced in recent years.

All active servers, services, and domains are automatically assigned an IPv4 address by GreggHost, which provides both IP address versions.

Multiple domains can share an IP address without difficulty. Using the GreggHost interface, a single Unique IP address can be issued to any fully hosted domain if necessary. Multiple IP addresses can be given to a domain’s domain name system (DNS) records.

DNS is analogous to a map or phone book in the same way that an IP address is similar to a phone number or street address. It maps easy-to-remember domain names to the IP address given to them. As a result of a server move, GreggHost can change the IP addresses assigned to a domain either manually or automatically.

Internet Protocol versions

The Internet uses two internetwork layer protocols, both of which GreggHost supports:

IPv4

The most extensively used protocol, with addresses limited to 32 bits (4 bytes) and typically expressed as four groups of decimal digits (e.g., 192.0.2.235). IPv4 has a maximum of 4.3 billion addresses, which is being surpassed as the number of devices connected to the Internet grows. Due to the restricted availability of IPv4 addresses, GreggHost charges an extra monthly fee for assigning a unique IPv4 address.

IPv6

A new protocol that uses a 128-bit addressing scheme, which is normally expressed as eight groups of hexadecimal digits (e.g., 2001:0db8:85a3:08d3:1319:8a2e:0370:7334). IPv6 was created to manage the Internet’s growth, and it allows for approximately 3.41038 addresses. Currently, GreggHost provides free Unique IPv6 addresses.

Adding a Unique IP address to a fully hosted domain

In some cases, adding a Unique IP address to a GreggHost-hosted domain may be useful or necessary. For more information, see the following article:

Finding a website’s IP address

You may examine your website’s IP address that GreggHost has assigned in your panel if you require it. For further information, see the GreggHost DNS article.

You can verify the propagation status of your domain by using one of the following links to see the IP address it is resolving to online:

whatsmydns.net – A well-known website that verifies DNS records all around the world.

Using GreggHost’s DNS propagation checker in the panel to view your GreggHost DNS entries.
