Why do we prefer subnet 192.168.1.0/24 to get more networks? Why not just make 192.168.2.0/24 another network and 192.168.3.0/24 another one

Why do we prefer subnet 192.168.1.0/24 to get more networks? --network #1 192.168.1.0/25 #2 192.168.1.128/25 I have not seen anyone else say that this is "preferred". There is no specific ...

Different subnet masks on same network

I am aware that one way to do this would be to have three vlans but as it stands, I am not able to connect them as such, because that would require a major rewiring. Usually the point of vlans is to ...

Different subnet masks on same network

Setting second network is for me the simplest way. I do not know why you thing in Windows is so hard to set. Here is the screen:

Wrong subnet configuration works anyway in a shared bus, but doesn't work in switched lan. Why?

I was told that this only works because the lan is a shared bus. If it was a switched lan This kind of distinction sounds to me like old material from the era when networks like ATM were competing ...

Allow access from 192.168.1.* to 192.168.2.*

Your current problem is the following (in layman's terms): Router 2 sends all destination IPs outside of 192.168.2.0/24 (or with whatever subnet mask you are using, I assume it's 24 bits) to router 1. ...

IPv4 Subnetting - Finding IDs for specific subnets

No one really answered this and I spent about an hour last night frantically searching for one because I also had this as a homework question. Since the first network will always be all zeroes in ...

Does adding a second IP as /32 with static routing cause any unintended issues?

No, it's a fairly normal configuration. (The address doesn't necessarily need to be on eth0, as the router will not make ARP queries for it, so it might be more typical to have such /32's on a "...

Multiple Interfaces on same subnet breaks PTP

PTP (IEEE 1588-2019) supports two different transports: Layer 2 and Layer 3 (UDP). UDP is by far the more common of the two, so I will assume you are using it. In that case, you are in a bit of "...

How to access LAN subnets from other subnets with interzone firewalling on the same router?

I wanted the net1 - 4 subnets to be sanely numbered, which is why lan's CIDR is /19, as my understanding (which may be incorrect) is if lan was set to a subnet mask encompassing the subnets of net3 - ...

It is widely used because it's the "first" address that comes to mind for a new network (and it's somewhat in the head of most tech persons as a default setting for new devices). But there ...

Setting IPs for multiple NICs on same server

Linux systems will, by default, answer ARP requests for IPv4 addresses belonging to any interface, not only the interface that the request was received on. If you have two interfaces in the same ...
