An IP address is a series of 4 numbers ranging from 0 to 255 separated by dots. Your IP address has been provided by your Internet provider. The IP address allows you to associate each computer with the Internet. This is called IP WAN (Wide Area Network).
But there are also series of IP addresses that connect your ADSL box to your printer, your TV etc ... It is called the IP LAN (Local Area Network). The IP WAN is accessible only with the devices connected to your ADSL box.
At the moment our My IP Tools system allows you to geolocate IP addresses and get information about V4 IP addresses. We call IP V4 the IP addresses composed of 4 numbers ranging from 0 to 255 separated by dots.
An IP address may also be associated with a domain name (eg www.my-domain-name.com).
It should be noted that each domain name must have an associated IP address, but it would be difficult to retain an IP address of this type: 122.245.302.128 to access a website. This is why domain names exist.
If, for example, you want to go to Google.com, you can access it by typing in your navigation bar: www.google.com or: 184.108.40.206
Be aware that an IP address may be fixed or dynamic.
As explained above, domain names have an associated IP address. This means that it is fixed.
As for your personal connection, the IP address may be fixed or dynamic. Be aware that some ISPs give you a fixed IP address and other dynamic.
The advantage of having a fixed IP address, allows you to connect equipment in your home to your box and to be able to access it remotely (home alarm, NAZ server, surveillance cameras ...).
The problem is that fixed IP addresses are the first targets of hackers.
For dynamic IP addresses, they change with the DHCP built into your ADSL box. DHCP will renew your IP address every 24 hours or 48 hours (approximately) according to the settings defined in your ADSL box.
