Yes, that is what the default gateway is used for.
The destination computer will likely send back an ICMP Destination Unreachable message to inform the source computer that there is no process listening on the specified port. The source computer can then take appropriate action based on this response, such as notifying the user or terminating the connection attempt.
No, it is not. A destination IP address may be any address, usually on a completely different network. The default gateway address is used to determine where to send packets that need to be routed outside of the current local area network.
When users sign into the internet they may not realize they are using a series of gateways to access their favorite websites. A default gateway is used a lot in office settings where a lot of computers need to be connected to both their internal network and the internet.
The default gateway refers to the "next-hop address"; the server or router your computer has to send packets to, to connect with the outside world. If the default gateway is not configured correctly, the usual symptoms are that your computer can connect within the local network, but it can't connect to the outside.You have to obtain the address which you should assign as the default gateway from your network administrator, or from your ISP.The default gateway refers to the "next-hop address"; the server or router your computer has to send packets to, to connect with the outside world.

The reserved address block for default routing is typically the address 0.0.0.0/0 in IPv4. This block is used to specify that a packet should be forwarded to the default gateway when there is no specific route for the destination address. In IPv6, the equivalent is ::/0. Default routing is essential for directing traffic outside of a local network when no more specific route exists.
Destination MAC: 0030.8517.44C4 Default gateway: 172.16.1.1
Before sending a packet, IPv4 establishes contact with the destination by using the Address Resolution Protocol (ARP) to map the destination IP address to a MAC (Media Access Control) address on the local network. If the destination is on a different network, IPv4 sends the packet to the default gateway, which is determined by the subnet mask. The packet includes the destination IP address, and the network layer handles routing it through the appropriate paths until it reaches the destination.
A Default gatewayis a node (a router) on a TCP/IP Network that serves as an access pointto another network. A default gateway is used by a host when the ip'spacket destination address belongs to someplace outside the local subnet.Without a default gateway you will not be able to route packets outof your LAN
If I am reading your question correctly, I would imagine it is because the computer is not on the same network... **The computer has an invalid default gateway address**
Who you are on the computer can usually be an anonymity, you can be anyone you want. In internet working you are a host. You view and receive data from the internet. Your identity is your IP address. Your IP address is your default gateway to the internet that's who you are.
If we are using public ip address, we can browse the internet. If it is having an intranet address a gateway is needed as a router or firewall to communicate with internet.***********************************************Without default gateway you cannot browse internet. It doesnt matter if you are on public or private network. Default Gateway is required to route your IP packets from your network to the other networks.
When a computer assigns itself an Automatic Private IP Addressing (APIPA) address, it typically does not include a valid default gateway address. APIPA is used when a device fails to obtain an IP address from a DHCP server, allowing it to communicate with other devices on the same local network segment. The assigned IP address falls within the range of 169.254.0.1 to 169.254.255.254, but without a default gateway, the device cannot access external networks, such as the internet.
