192.168.50.0/24 — the ASUS default LAN
192.168.50.0/24 is the subnet ASUS ships on its routers: 256 addresses, gateway at 192.168.50.1. If you bought an RT-, ROG or ZenWiFi model in the last decade and never touched the LAN settings, this is your network.
ASUS picked an uncommon /24 on purpose. 192.168.1.x and 192.168.0.x are where ISP modems and older routers live, so choosing 50.x means an ASUS box plugged behind existing gear rarely conflicts with it.

Reaching the admin panel
Two ways in: browse to 192.168.50.1, or use router.asus.com — a magic hostname the router answers itself via its own DNS, so it keeps working even after you change the LAN subnet. The same interface serves ASUSWRT management and AiMesh node configuration.
Living inside it
The defaults follow the standard /24 playbook: DHCP pool across the upper half of the range, static leases for your NAS and printers below it. If you ever VPN into an office or chain a second router, check for overlap — 50.x collisions are rare, which is the entire reason ASUS chose it.

Frequently asked questions
What is 192.168.50.1?
The default LAN IP and admin address of ASUS routers — the ASUSWRT management page. The alias router.asus.com reaches the same place regardless of your LAN subnet.
Why does ASUS use 192.168.50.x instead of 192.168.1.x?
Collision avoidance. ISP modems and older routers crowd 192.168.0.x and 192.168.1.x, so ASUS moved its default to a quiet /24 to keep double-router setups working out of the box.
How do I change my ASUS subnet?
In ASUSWRT under LAN, then LAN IP: set a new address and subnet mask and the DHCP range follows. Devices pick up new leases when they reconnect.
