Before coming to differences between 192.168.1.1 & 192.168.0.1, you have to know what those numbers mean.
Some of you already know those are IP addresses, IPv4 addresses to be specific.
Just below, we are going to explain what they mean and why are they different.
Now some IP addresses are reserved as Private IPs for use in-home or business networks internally. The private IP Addresses, as reserved by the Network Information Centre, can be ranged as given below:
Class A: 10.0.0.0 to 10.255.255.255: These are used in very large organizations with a large number of nodes or devices.
Class B: 172.16.0.0 to 172.31.255.255: These are used in medium to large organizations with a sizable number of nodes or devices.
Class C: 192.168.0.0 to 192.168.255.255: These are used in home and small organizations with a limited number of nodes or devices.
As evident from above, 192.168.1.1 & 192.168.0.1 are both Class C IP addresses.
Now, IPv4 has 4 parts each separated by a dot.
In Class A, the first part denotes network address and the next three denote host addresses.
In Class B, the first 2 parts denote network address and the next two denote host addresses.
In Class C, the first 3 parts denote network address and the last part denotes host address.
Both the IPs being Class C, the first 3 parts denote network address. Hence the two networks 192.168.1.X & 192.168.0.X are entirely different networks, for which you have to know subnet masks to identify the Private IP Addresses.
Usually, the IP addresses are assigned in routers. There is a common belief that .1.1 is better than .0.1 in terms of network capability.
But, that is wrong! They are just two random private IP addresses traditionally used in routers. If your router provides DHCP service, the IPs are assigned dynamically and don’t really matter what IP is assigned.
This depends on the brand of the router and can be different in different brands.
But why they are used in routers?
Mostly because they are private IPs, which means they are not assigned to any organization. And secondly, they are of the lowest range i.e. the starting of IPs in Class C IP Addresses. So that was a convention earlier followed, of which we can find many deviant nowadays with router IP ranging from 192.168.1.254 to 10.0.0.2 i.e. any IP from the private IP range.
Now if your router IP changes in DHCP settings, you don’t have to worry. It is alright. And in case you find something wrong with changed IP, you can always reset the IP, which will prompt the router to change it to default settings.
So earlier if you were torn between 192.168.1.1 & 192.168.0.1 you now know what those are random private IP addresses, which were conventionally used in routers and also understand the difference between them arises from the fact that they denote different private networks. So be it a router problem or just quenching your knowledge thirst, you can now confidently navigate among your options.
