No, you cannot. The gateway IP tells the system how to get to another subnet, and without it, packets won’t leave the current subnet. A computer only knows how to talk to the other computers that are directly connected on the same subnet.
Do you need a gateway for each subnet?
You don’t need a router. If you set the subnet mask on all of the PCs to be 255.255. 0.0, then they should all be able to ping each other. Basically, opening up the subnet mask puts all of the PCs on the same subnet, so a router isn’t needed.
Does each subnet have its own default gateway?
The default gateway always resides in the same subnet as the end device IP. The gateway can really be any unique address within the subnet itself, but most network administrators designate the first number of the subnet as the gateway.
Can you have two subnets on the same router?
1) It is possible to have multiple subnets “behind” one router; the Internet would be a very broken place with millions more routers needed if it were not. However, your example of using a /16 subnet mask on the LAN interface, with many /24’s connecting to it, is not exactly how it would actually function.
Can multiple devices have the same gateway?
1 Answer. Though there are some exceptions to this in unusual setups, the general answer is no. You cannot configure your computer to use a gateway that is on a different subnet. You cannot reach devices on other subnets without going through a router (gateway).
Should IP address and gateway be the same?
1 Answer. No, it cannot be the same. Yes, you can change netmask, but you need to do that on every computer/device having an IP address on the network, otherwise part of the machines in the network cannot be reached.
How many subnets can a router have?
Figure 3 shows the 172.16. 0.0 network, with the third grouping as the Subnet ID. Four of the 256 possible subnets are shown connected to one router. Each subnet is identified either by its Subnet ID or the subnet address with the Host ID set to .
Is default gateway same as router?
A gateway and a router are essentially the same. The term “default gateway” is used to mean the router on your LAN which has the responsibility of being the first point of contact for traffic to computers outside the LAN.
Can gateway be outside subnet?
8.8 it gets there but through the old gateway, using tracert 10.0. 0.1, it reaches 10.0. 0.1). I believe the default gateway setting is being overridden by the static route table on the layer 3 switches.
Is the subnet ID the same as the gateway?
The subnet mask splits the IP address into the host and network addresses, thereby defining which part of the IP address belongs to the device and which part belongs to the network. The device called a gateway or default gateway connects local devices to other networks.
Can different subnets be on the same switch?
You can use the same switch for multiple subnets, but you need to you VLAN’s that is what they are there for, unless you switch won’t support VLAN’s. First time your switch gets a MAC address back that has an IP addresses in more than one subnet it’s gonna freak out.
Can two subnets talk to each other?
Are you referring to two subnets on the same VLAN, from your previous question? Sorry for the hairsplitting, but your question asks for, why devices in different subnets can’t talk. The answer is: yes, they can talk.
Can you subnet with one router?
A single network can also be subnetted. Subnetting takes a single network and subdivides it into smaller networks.These interfaces will have an IP address on them that will become the default gateway address for each subnet, and the router will route traffic between the subnets and out to the Internet.
Can you have 2 default gateways?
No, it can’t have more than one active default gateway. Any operating system can have multiple default gateways configured (technically a route to the unspecified address, i.e. 0.0. 0.0 or :: ).
How do I connect two subnets?
How to Connect Computers That Are on 2 Different Subnets
- Connect the computers to the network.
- Connect the routers to each other.
- Enable a routing protocol in each subnet’s router.
- Allow time for the routing tables to update.
Is default gateway same for all computers on network?
The networking software stack of each computer contains a routing table that specifies which interface is used for transmission and which router on the network is responsible for forwarding to a specific set of addresses.It serves as the default gateway for all network devices.
Can DNS and gateway be the same?
Domain Name Service (DNS) numbers are IP addresses that a workstation or server uses to refer to specific servers that resolve domain names to IP addresses. A gateway IP refers to a device on a network which sends local network traffic to other networks.
Does router need default gateway?
Default Gateway is used when the host doesn’t have any route information for a particular packet. So it will ask the default gateway. Now for a router there will be lot of static routing information, but if the router is not able to find a routing information, it should take the route mentioned in 0.0.
Is broadcast and gateway the same?
A broadcast address is the one that is used by one host to communicated to another host on the same network whereas the default gateway is this address that is used by all hosts to communicate with hosts outside the network/subnet. Traffic destined to other computers on another network is routed through the gateway.
Can you have multiple VLANs on the same subnet?
1 Answer. Of course you can do that, but it is not the recommended way. VLANs use software to emulate separate physical LANs. Each VLAN is thus a separate broadcast domain and a separate network.
What subnet should I use?
Most home networks use the default subnet mask of 255.255. 255.0. However, an office network may be configured with a different subnet mask such as 255.255.This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256).
