Ok, this explains subnet addressing which is useful if you run a scanner, a firewall, a router or anything else that is bound to IP subnet addressing. Note that this only describes IPv4 subnets. Reading binary values
Normally, you read binary numbers bytewise (8 bit wise). Start at the last bit, bit 0. If it is 1, add 2^0 to your number, else add 0. Then the next bit, bit 1, If it is 1, add 2^1 (2) to your number, If bit 3 is 1 add 2^2 (4) to your number, if bit 4 is 1 add 2^3 (8) to your number ... if bit 8 is 1 add 2^7 (128) to your number. You see, the base is always 2 because it can be either 0 or 1. Example 1: 10100100 = 2^7+0+2^5+0+0+0+2^2+0+0 = 164 Example 2: 11111111 = 2^7+2^6+2^5+2^4+2^3+2^2+2^1+2^0 = 255 Thats it! Now to subnet addressing.
When you state a host including a subnet (example: nmap), you do it like this: 1.2.3.4/24, where /24 is the subnet. Lets have a look at what this means: an IP address is a 32 bit address. It is divided into 4 bytes (each 8 bits meaning they can be 0 to 255) in general notation:
00000001 00000010 00000011 00000100 = "1.2.3.4"
now, IP uses one part of this address to specify which Net it is on. Most of the time, this is a physical Net like an ethernet LAN that is linked to the internet. Nets that link to the internet get dedicated IPs for each of their hosts from the IANA.org. /24 means that the first 24 bits are the Net address and the remaining 8 bits are the Host address. This looks like this: Net: 000000010000001000000011 Host: 00000100 Meaning, we are on the net 1.2.3.0 (0 used as a wildcard here) and on the host 4 of 256.
SUBNET MASK: In this case, the subnet mask would be 255.255.255.0. A subnet mask is created simply by filling all NET address bits with 1 and the HOST bits with 0. (11111111 = 255). There are 4 "Classes" on the Internet, which are the standard Subnets. *Class A: "0" + 7 net bits + 24 host bits, hosts 0.0.0.0 to 126.255.255.255 Net IDs: 0 0000000 to 0 1111111 (which is 127 => 127.0.0.0 reserved for local loopback)
*Class B: "10" + 14 net bits + 14 host bits, hosts 128.
6. The destination address for the DHCP client and server are both 255.255.255.255. The source IP address for the client is 0.0.0.0, while the server uses its own actual IP address as the source.
Address lines show the source and end-point of the data on the data lines. Control lines are used in starting the bus protocol. Normally there are lines

IPv4 is the original internet addressing system. It is a protocol which was used on packet-switched networks. Delivery model is how it operates at its best without a guaranteed avoidance of duplicate in delivery or assurance of proper sequencing. Some aspects include data integrity which is mostly addressed by TCP. IPV4 uses binary notation to sort at time IP address that consist of 32 bits. It is a practice to convert the 32 bits of an IPv4 address into four 8 bit known as octets. With each octet converted to a decimal number (base 10) from (0–255) and parted by a period developed a format called dotted decimal notation. IPv4 has a category of address class types: Class A, B, C, D and E. The class A addresses are used for big networks and always start with zero bits. Each Class A address network can hold up as many as 16,777,216 hosts.
1) The Female (Pwo) Mask is used in celebrations celebrating the Chokwe people’s women. This Pwo Mask was made in the late 19th to early 201th century and is made of wood, fiber, pigment, and metal. The creators of the mask, the Chokwe peoples, live in the Democratic Republic of Congo.
IP – The Internet Protocol (IP) - is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.
Masking is it a good thing or is it a bad thing. Masking is when an individual modifies their behavior or personality to adapt to different issues. People tend to mask their feelings to hide their emotions from others. Some people use masking to cover up their feelings from when they are being disrespected and want to retaliate. Social pressures, harassment, embarrassment, physical or mental abuse are a few issues that causes an individual to mask themselves. The purpose of this essay is to examine the cycle of oppression Claude McKay’s “If We Must Die” in comparison to Paul Laurence Dunbar’s “We Wear The Mask” in regards to the poets understandings about concealing their feelings, being oppressed, and character.
“Be a man”, is on of the most destructive phrases to tell boys and men. The Mask You Live In explains the struggles boys and men have growing up in a patriarchal society. I chose to watch this to understand how men feel oppressed. All year, I became aware of females and their struggles in the patriarchy. It is interesting to see that men are affected too. The documentary should have had more personal stories because it allows the audience to connect with and have empathy for men. On the other hand, the movie thoroughly demonstrated the inner conflict boys and men face in society. Men feel they must be strong and dominate. They feel they need to hide emotion and empathy in order to fit in. They must be manly in order to
Data is transmitted over the Internet in packets through a protocol called TCP/IP. A set of rules called an access control list (ACL) determines which packets are allowed in and which are dropped. Stateful packet filtering examines the header of each packet in isolation. Deep packet filtering examines the data in the body of a packet to provide more effective access control. Deep packet filtering is the heart of a new type of filter called intrusion prevention systems.
TOR (Roger Dingledine) is a circuit based low-latency anonymous communication service. TOR is now in its second generation and was developed from the Onion routing program. The routing system can run on several operating systems and protect the anonymity of the user. The latest TOR version supports perfect forward secrecy, congestion control, directory servers, integrity checking and configurable exit policies. Tor is essentially a distributed overlay network which works on the application layer of the TCP protocol. It essentially anonymizes all TCP-based applications like web-browsing, SSH, instant messaging. Using TOR can protect against common form of Internet surveillance known as “traffic analysis” (Electronic Frontier Foundation). Knowing the source and destination of your internet traffic allows others to track your behavior and interests. An IP packet has a header and a dat...
Shakespeare used many literary devices throughout his history to create timeless classics. Much Ado About Nothing is no exception. He used things such as themes, symbols and motifs to create this effect. Masking is the prominent motif in Much Ado About Nothing. It is seen many times over in this play. There are two kinds of masking that Shakespeare used in Much Ado. One is literal masking, this where a character actually wears a mask during the play. This is seen several times. There is also another form of masking that was used in Much Ado About Nothing, this is literary masking and this is when characters hide and/or makeup plots to put into others heads for a benefit or a cause.
In using NAT, hosts on the Internet appear to be communicating directly with the NAT device rather than with the actual host inside the private network. Inbound packets are sent to the NAT device's IP address and the device changes the destination packet header from its own Internet address to the private network address of the true destination host. The result is that, in theory, a single globally unique IP address is used for hundreds, thousands, or even millions of privately addressed hosts. In practice, however, there are drawbacks. For one thing, many Internet protocols and applications depend on the network being truly end-to-end, with packets forwarded entirely unmodified from the source to the destination.
IP address is you Internet identity when you are connected to the web. It is synonymous to a postal address.
