192.168.1.0/24 — the default home subnet
192.168.1.0/24 is very likely the subnet you are on right now. Linksys, Netgear, TP-Link and a long tail of other vendors ship their routers with the LAN on 192.168.1.x, making this 256-address slice of the 192.168.0.0/16 private block the most deployed subnet on the planet.
The conventions inside it are nearly universal: the router takes 192.168.1.1 as the gateway (some ISPs use .254), and the DHCP pool hands out the rest to phones, laptops and smart TVs.

Anatomy of a default LAN
The router sits at the bottom of the range and acts as gateway, DNS forwarder and DHCP server in one box. Typical pools start at 192.168.1.100 and run to .199 or beyond, leaving the low numbers free for anything you want to pin statically — a NAS at .10, a printer at .20. Keep static assignments below the pool start and you will never fight DHCP over an address.
IP conflicts and other folklore
The classic failure is two devices claiming the same address: someone hard-codes 192.168.1.50 without excluding it from the pool, DHCP later hands .50 to a phone, and both devices intermittently fall off the network. The fix is boring — reservations, or statics outside the pool — but the works-then-doesn't symptom has launched a thousand forum threads.
When to renumber
One good reason to leave 192.168.1.x behind: VPN collisions. If your employer's office LAN is also 192.168.1.0/24, connecting the VPN creates overlapping routes and breaks local printing, NAS access or the tunnel itself. Moving your home LAN to something eccentric like 192.168.73.0/24 permanently sidesteps the clash.

Frequently asked questions
What is 192.168.1.1?
The default gateway address of this subnet — your router's LAN IP. Browsing to it opens the router's admin interface on most consumer gear.
How many devices fit on 192.168.1.0/24?
254 usable host addresses: 256 total, minus the network address 192.168.1.0 and the broadcast address 192.168.1.255 — far more than any household needs.
Why can't I reach 192.168.1.1?
Either your network uses a different subnet (check your own IP and gateway), the router was renumbered — many ISPs use .254 or 10.0.0.1 — or you are behind a second router doing its own NAT.
Should I change my network from 192.168.1.0/24?
Only for a reason: VPN or site-to-site collisions with another 192.168.1.x network are the usual one. Otherwise the default is fine — obscurity is not security, but collision avoidance is uptime.
