Does Restarting Router Change IP? – A Comprehensive Guide
When it comes to understanding how your router works and setting up your home network, there are countless questions that can arise. One of the most burning questions is whether restarting your router causes your IP address to change. In this guide, we’ll delve into the world of DHCP, IP addresses, and router settings, diving into the intricacies of what restarts your router and whether it affects the visibility of your online activities.
First, Let’s Understand What Exactly Happens When You restart Your Router
When you restart your router or device, it initiates a process similar to a reboot. The router briefly disconnects from the internet, completes a series of internal checks, recycles its memory, and once again connects to the internet. If you’re connected to a network before restarting, you’ll be disconnected first, and then reconnected – this is known as a ‘DHCP lease renewal.’
**What is DHCP?
DHCP (Dynamic Host Control Protocol) is a protocol that assigns specific IP addresses to devices on a network. On your router, DHCP is enabled so that it can automatically assign network settings to devices connected to it. To put it simply, DHCP grants your device an IP address for browsing the internet, sending emails or any other online activity.***
So, Does Restarting Really Change Your IP Address?
In all likelihood, yes, restarting router does change your IP address. When router restarts, it requests a new PUBLIC IP address from your Internet Service Provider ISP. This new IP address is likely to be different from the one you’re currently using. This is because YOUR ISP maintains a pool of public IPS, and when you restart yours, it’s assigned a new 1 from this pool. On the other hand, your internal LAN-based IP address remains the same, assuming you have a static and not dynamic IP.
Before we dive deeper, let’s illustrate this concept with a simple schema:
| Router State (Before Restart) | RouterState (After Restart) |
|---|---|
| Public IP (E.g., 192.168.x.x) | New PublicIP (E.g., 192.168.something) |
| same LAN IP (E.g.,10.0.0.1) (static or dynamic), | same LAN IP still (E.g., 10.0.0.1) |
What Changes When You Restart Your Router? Beyond IP Addresses
When you restart a router, several other settings are affected for the following reasons:
- Dynamic DNS (DDNS) updates if you have a dynamic IP registered with a DDNS service.* Your router may connect to the internet, and your IP lease is renewed.
- Dynamic Host Configuration Protocol (DHCP) addresses are reassigned to devices; this includes IP addresses set for your devices.
- Your Wireless Network Settings (SSID, Channel).
- Router’s firmware updated (if available).
Take note that some of those changes might not occur immediately after reconnecting. Your router may need multiple attempts to re-establish connections because of network congestion or other unexpected issues.
What If Changing Your Router’s IP Address Won’t Work? If You Need to Bypass Internet Restrictions
In some unique situations, you might need to by-pass internet restrictions or reset ISP restrictions. Here are a few helpful tips:
- Reset Routers: In some browsers, you can reset your router by releasing and renewing your IP address. Please note that this will only work based on your router’s capabilities with DHCP.
- Change Router Defaults: If you need to bypass restrictions when using a new router, consider reviewing the default settings for your router. Modifying these settings can help bypass content restrictions.
- Contact Your Network Administrator: If you’re having restrictions imposed by your network administrator, then you should reach out to them for assistance addressing the issue.
Conclusion
Recapitulating, restarting Your router does change your public IP address through the process of DHCP lease, but your internal LAN IP maintains its static or dynamic setting by default. Other settings like Your Wireless Network Settings, DDNS updates, and firmware updates may result from restarting your router. Keep tabs on your router’s settings and your behavior online, and you’ll be well-insulated from potential risks.
Finally, if you have any questions or concerns during your router configuration, please don not hesitate to consult the manufacturer’s knowledge base or seek assistance from your network-administrator.
