- The network ID is 24 bits long.
- The host ID is 8 bits long.
- 2^21 = 2097152 network address
- 2^8 – 2 = 254 host address
- Within any network, the host ID must be unique to that network.
- Host ID in which all bits are set to 0 cannot be assigned because this host ID is used to represent the network ID of the IP address.

What is a network ID?
A network ID, in the world of Transmission Control Protocol/Internet Protocol or TCP/IP, is the portion of the TCP/IP address which identifies the network for a given host, usually composed of three octets with dotted decimal representation.
What is the difference between network and host address?
The Network address identifies the specific network to which host is attached, and Host address uniquely identifies a host within a network. The distinction is important because router routes the packet according to a network address and don't care about host address.
What is network and host in IP address?
An IP address consists of two components: the network address and the host address. The network address is used to find the subnet in which the computer or the device is located and the host address is used to find the computer or the device in the subnet.
How do I find my network ID?
To calculate the Network ID of a subnet, take an IP address within the subnet and run the AND operator (on a calculator) on the subnet mask. Using a calculator to find the Network ID is the easy way as you do not have to convert it into binary form. Once the Network ID is found, calculating the Broadcast ID is easy.
Which is network and host?
Nodes, hosts, and servers A network node is any device participating in a network. A host is a node that participates in user applications, either as a server, client, or both. A server is a type of host that offers resources to the other hosts.
What is a 255.255 255.0 subnet?
A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.
What is host number?
On a TCP/IP network, each host has a host number that, together with a network identity, forms its own unique IP address. In the Open Systems Interconnection (OSI) model, protocols in the transport layer, also known as Layer 4, are responsible for communication between hosts.
What does the subnet mask 255.255 255.0 tell a router?
What does the subnet mask 255.255. 255.0 tell a router? The purpose of the part of the mask that reads 255, or all 1s in binary, is to tell a router what part of an IP address is the subnet ID.
What is network based IDS?
Network based IDS: these types of IDS are strategically positioned in a network to detect any attack on the hosts of that network. To capture all the data passing through the network, you need to position your IDS at the entry and exit point of data from your network to the outside world. You can also position some IDS near ...
What are the two types of IDS?
Depending on how they function, network based IDS can be divided into two types: 1 Statistical anomaly IDS 2 Pattern matching IDS
What is the purpose of IDS model?
In statistical based IDS model, the IDS try to find out users’ or system’s behavior that seem abnormal. Actually, IDS make a profile of every user and system during the normal operation time. When the deviation of this normal behavior is detected the IDS trigger its alarm for intrusion. One of the main advantages of this type of IDS is that they can detect the type of intrusion that has no records of its previous occurrence. In that sense, statistical anomaly can detect new type of attack patterns. A large number of false alarms are the main problem with this system.
What is the problem with pattern based IDS?
The main problem with pattern based IDS is that they cannot detect anything that is unknown to them or that of which they have no data in their pattern matching database. Since there are many network based exploits coming on each month, the need to be updated frequently. Some popular Network based IDS are: Real Secure.
Can a host based system monitor all users?
They can monitor all users’ activities which is not possible in a network based system. They are capable of identifying attacks that originate from inside the host. A host based system can analyze the decrypted traffic to find attack signature-thus giving them the ability to monitor encrypted traffic.
Do a host server need extra hardware?
They do not require any extra hardware since they can be installed in the existing host servers. They are cost effective for a small scale network having a few hosts. The main disadvantages of this system are they can be compromised as soon as the host server is compromised by an attack.
Can IDS be used for host based network?
There are not straightforward way to decide which type of IDS will work best for your network since both types of IDS has its plus and minus points. You can find that in some cases, deploying both types of IDS can be beneficial such as network based IDS can provide security to your overall network, while you can deploy host based IDS to your hosts with sensitive data.
Compare host IDS vs. network IDS through the pros and cons of each, and learn how more modern systems may be better suited to ensure effective enterprise security

What is a host ID?
A host ID uniquely identifies a host within an address family on a network but does not identify the network. A host ID is not necessarily sufficient to establish communications with a host.
What is the network ID?
Its very simple mate.The network id is the id of the network & resembles the network.The host id is the identification of the host in the network.#N#Class A:Network.Node.Node.Node#N#Class B:Network.Network.Node.Node#N#Class C:Network.Network.Network.Node#N#The above is the way upon which its classified depending upon which Class the IP address belongs to.#N#If there is a network with a number of subnetted networks.How will a packet arriving at the default gateway/router determine where it should go?#N#It all comes down to the "network id" [net id] portion which makes it possible to locate the network.The packet would then traverse its way through a switch/hub to the appropriate host with the help of the host id.#N#Always remember routers dont care about hosts,all they care about is segmented networks.#N#I hope this helps.
What is a host device?
A host is any device from which information can be sent or received. So a camera, a server, a laptop/desktop, a printer, etc.
What is the IP address of a router?
The Network IP would really be 192.168.1.0. You've identified the router's IP address.
What is the subnet mask of 192.168.1.128?
So... a host is 1 ip assigned to a resource... say 192.168.1.129 while the network is 192.168.1.128 /25 Actually knowing the network is 192.168.1.128, you should be able to infer the subnet mask is /25.
What is the first IP address?
The first IP (.0 in your example) is called the network identifier and is used to identify the subnet. You can't actually give a host on the network that IP though.
How many IP addresses are in a subnet?
Each subnet has two IP addresses that can't be assigned to an actual device (a host), which include the first and last IP addresses in the subnet range. The last IP (.255 in your example) is called the broadcast address.
Does a network have an IP address?
Network in general does not have an IP. It does have subnet number which is the first 3 groups of the IP number. Each device on the Network has its own unique IP number (the x in the end). x can be a number from 0 to 255.
Do you need to know the broadcast address?
Yes very true . You really do need to know the broadcast address to be really sure.
What is the difference between IP address and network ID?
To network ID or host ID that is the question. An IP address consists of two components: a network ID and a host ID . The network ID identifies the network segment to which the host belongs . The host ID identifies an individual host on some specific network segment. A host can communicate directly only with other hosts on the same network segment.
Why are domain names and NetBIOS names more friendly?
As you may already know, domain names and NetBIOS names are even more friendly because they use symbolic names that make sense to humans. An IP address requires 32 binary digits and defines a 32-bit address space that supports nearly 4.3 billion unique addresses.
How does a router work?
A router moves packets from one subnet to another. In addition, a router reads the network ID for a packet's destination address and determines whether that packet should remain on the current subnet or be routed to a different subnet. When a router delivers a packet to the correct subnet, the router then uses the host ID portion ...
Can a host communicate with other hosts?
A host can communicate directly only with other hosts on the same network segment. A network segment is a logical division of a network into unique numeric network IDs called subnets. A host must use a router to communicate with hosts on other subnets. A router moves packets from one subnet to another. In addition, a router reads the network ID ...
What is an interface in a network?
An interface connects a computer or a networking device to the network. In a computer network, all interfaces must be configured with unique IP addresses. If two or more interfaces are configured with the same IP address, the network will not work.
What is the IP address of a computer?
Addresses in computer networks are known as IP addresses. An IP address consists of two components: the network address and the host address. The network address is used to find the subnet in which the computer or the device is located and the host address is used to find the computer or the device in the subnet.
How many versions of IP addresses are there?
There are two versions of IP addresses: IPv4 and IPv6. The length of IP addresses is different in both versions. Both versions also use different formats to differentiate between network addresses and host addresses. Let's understand IP addresses in both versions.
Why do computers use IP addresses?
In a busy network where interfaces process millions of packets per second, an overlap of IP addresses can bring the entire network down. To avoid such a situation , computer networks use a unique IP address on each interface.
Is IP address ambiguous?
An IP address is always used with the subnet mask. Without the subnet mask, an IP address is considered an ambiguous address.
Do IP addresses always have to be written before host addresses?
In IP addresses, network addresses are always written before host addresses. If we write the network address before the host address of a PC, we will get the IP address of that PC. The following image shows this process in our example network.
