An IP address (Internet Protocol) is a unique numerical identifier assigned to every device connected to the Internet. It allows devices to recognise each other and communicate across the global network.
There are two formats: IPv4 (4 numbers separated by dots, e.g. 192.168.1.1) and IPv6 (8 hexadecimal groups, e.g. 2001:db8::1).
A static (fixed) IP address stays the same at every connection. Ideal for hosting a server or reliable remote access.
A dynamic IP address changes regularly (at each connection or periodically). Most residential broadband subscriptions use dynamic addresses.
To track changes to your IP, bookmark monip.lws.fr and check it regularly.
The IPv4 protocol allows around 4.3 billion unique addresses — insufficient given the explosion of connected devices.
IPv6 was designed to solve this: it offers 340 sextillion unique addresses (2128), a virtually unlimited supply.
The transition to IPv6 is gradual: many devices now support both protocols simultaneously (dual-stack).

Everything you need to know about IP addresses, geolocation and online privacy.
IPv4 (e.g. 192.168.1.1) is the original format, limited to around 4.3 billion addresses — a pool exhausted since 2011. IPv6 (e.g. 2001:db8::1) was designed to fix this: it offers 340 sextillion addresses, a virtually unlimited reserve.
Your public IP address is visible to every server you communicate with: websites, online games, messaging apps. This is fundamental to how the Internet works — without a sender IP, replies could not reach you. However, your private IP (local network) is never exposed externally.
Most ISPs assign dynamic IPs: they can change at each reconnection or after a period of inactivity. This is common practice to optimise the available address pool. If you need a stable IP (hosting, remote access), your ISP usually offers a static IP as a paid add-on.
No. IP geolocation is approximate: it typically indicates the city or region where your ISP's infrastructure is located, with around 50 km accuracy. It never reveals your home address or precise GPS position.
Several options exist: a VPN replaces your IP with the VPN server's address (simplest for everyday use), the Tor browser routes your traffic through multiple relays for better anonymity, and a proxy can also act as an intermediary. These tools reduce your digital footprint but do not provide absolute anonymity.
An ASN (Autonomous System Number) is a unique identifier assigned to a network managed by a single organisation on the Internet: ISP, company, hosting provider, etc. For example, AS15169 belongs to Google. It identifies which operator owns a block of IP addresses.
The hostname is the result of a reverse DNS lookup (PTR record): it maps an IP address to a readable domain name. For example, IP 8.8.8.8 resolves to dns.google. Not all servers configure a PTR record — its absence is normal for residential connections.
Your public IP is the one visible on the Internet, assigned by your ISP to your router or box. Your private IP (e.g. 192.168.x.x or 10.x.x.x) identifies your device within your local network. Your router translates between the two using a mechanism called NAT.
