Most ISPs assign dynamic IP addresses. Your IP may change each time your modem is restarted or reconnection occurs. If you need a fixed IP, request a static IP package from your ISP.

IP Addresses Explained: IPv4, IPv6, Static and Dynamic
What is an IP address, how does it work, and why does your website's IP structure matter — technical guide.
What is an IP address?
An Internet Protocol address is the unique numerical identifier assigned to every device connected to the internet. It comes in two versions: IPv4 (e.g. 192.168.1.1) and IPv6 (e.g. 2001:db8::1).
Browse the knowledge base →What is the difference between IPv4 and IPv6?
IPv4 supports approximately 4.3 billion addresses with its 32-bit structure. IPv6 offers a virtually unlimited address space with 128 bits. Modern infrastructure supports both protocols.
Browse the knowledge base →Can you find a location from an IP address?
IP-based geolocation (GeoIP) typically gives a city-level approximate result. It cannot provide an exact address and may be off by several km depending on ISP infrastructure.
Browse the knowledge base →Static IP vs dynamic IP
A dynamic IP changes when the connection is renewed. A static IP remains fixed; it is preferred for corporate email servers, VPN infrastructure, and web services.
Browse the knowledge base →Shared IP vs dedicated IP
In shared hosting, multiple websites use the same IP. A dedicated IP is assigned exclusively to your site, providing advantages for email sending reputation, direct access by IP and IP-based allowlisting; it is not required for SSL (SNI).
Browse the knowledge base →What is Reverse DNS (rDNS)?
Reverse DNS is a lookup that resolves an IP address back to a domain name. Email servers require correct rDNS records to pass spam filters.

How to Flush DNS Cache?
If your site was updated but is not resolving to the new IP, flushing the DNS cache lets you see the latest DNS changes instantly.
Windows — DNS Flush
1
Open Command Prompt
Start → type cmd → Run as administrator.
2
Flush DNS cache
ipconfig /flushdns
3
Renew IP address (optional)
ipconfig /release ipconfig /renew
4
macOS Terminal command
sudo dscacheutil -flushcache && sudo killall -HUP mDNSResponder

Why does my IP address keep changing?
How do I find a website's IP address?
Type the domain name (e.g.
atakdomain.com) into the lookup box on this page and click Look up. The tool shows the domain's current IP address, hosting provider and location in real time.What is the difference between a public and a local IP address?
Your public IP is the address your ISP assigns to your router; every website you visit sees it, and it is the address this IP lookup shows. Your local (private) IP is the internal address your router gives each device on your home or office network, usually
192.168.x.x or 10.x.x.x, and it is not visible from the internet. That is why the IP in your computer's settings can differ from the one this tool shows.What is IPv6?
As the internet spread, IPv4 addresses were quickly exhausted. IPv6, developed by the IETF in the mid-1990s to solve this problem, offers approximately 3.4×10^38 different IP addresses. IPv6 addresses are shown in the
2001:db8::1 format, and modern internet infrastructure can run both protocols simultaneously (dual-stack).What is the difference between shared and dedicated IP?
In shared hosting, all sites on the same server share one IP. A dedicated IP is assigned only to your site, providing advantages for email reputation, direct access by IP and IP-based allowlisting; it is not required for SSL/TLS (SNI).
Can my exact location be found from my IP address?
IP-based geolocation (GeoIP) generally gives an approximate city-level result; it cannot provide an exact address or postcode. When using a VPN or proxy, the shown location may differ from your real location.
How do I flush the DNS cache?
Windows: Start →
macOS:
cmd → Run as admin → type ipconfig /flushdns. Then run ipconfig /release and ipconfig /renew.macOS:
sudo dscacheutil -flushcache && sudo killall -HUP mDNSResponderCan a domain be found from an IP address?
Yes, you can find the PTR record registered to an IP address using Reverse DNS (rDNS) lookup. For more comprehensive information, use our Whois Lookup tool.
What is my IP address?
Your IP address is the public address your internet provider assigns to your connection, and every website you visit sees it. The Atak Domain IP lookup shows it within a few seconds of opening the page, as IPv4 or IPv6 (whichever your connection uses), together with your ISP and approximate location. No sign-up needed.
What can you do with an IP address?
When you query an IP address you can obtain: geographic location (country, city), ISP, and ASN/Organization. Exact address identification is not possible.
How do I find my IP address on Windows, Mac, iPhone or Android?
The IP lookup shows your public IP within a few seconds of opening the page. For your local IP: on Windows, open Command Prompt and type
ipconfig (see “IPv4 Address”); on a Mac, go to System Settings → Network → your connection → Details; on iPhone, Settings → Wi-Fi → tap (i) next to your network; on Android, Settings → Wi-Fi → your network's details (menu names vary by manufacturer).How can I change my IP address?
1. Restart your modem: ISPs usually assign dynamic IPs; a new IP may be assigned after a reboot.
2. Use a VPN: Your real IP is hidden; the VPN server's IP is shown instead.
3. Use a proxy server: Websites see the proxy address instead of your real IP.
2. Use a VPN: Your real IP is hidden; the VPN server's IP is shown instead.
3. Use a proxy server: Websites see the proxy address instead of your real IP.
