sir about sa kanang mga security ang kana raman cgurong sa router need og strong password sa para dli maka sulod ang costumers.

Speaking of securities bro, naa daghan options kung walay server imu cafe,gamay ra man nakabalo unsaon pag access sa router settings and definitely secured naman na imu router kay naa man na security features like username and password(assuming you already configured it)kung wala pa imu ra na i-change password ang router, regarding sa imu mga PC recommended jud na imu i-deep freeze then disable porn site para dili ka access ang mga bata,secondly butangi password ang CMOS para dili mausab sa mga users ang imu settings..

Nag-libog jud ko unsa-on bro... Bogo kaaU ug ing-ani... Curious lang...

1. unsa man sad na ang Class A, B, C, and D bro?
2. unsa-on mana nato sila pag-identify and pag-apply?
3. kanus-a na nato sila magamit ang mga Class A, B, C, and D?
4. nganong Class A man ang commonly used?

Hope this may help you:

Internet Protocol Tutorial Classes of IP Addresses, IP Broadcast and IP Multicast
IPv4 Address Classes

The IPv4 address space can be subdivided into 5 classes - Class A, B, C, D and E. Each class consists of a contiguous subset of the overall IPv4 address range.

With a few special exceptions explained further below, the values of the leftmost four bits of an IPv4 address determine its class as follows:
Class Leftmost bits Start address Finish address A 0xxx 0.0.0.0 127.255.255.255 B 10xx 128.0.0.0 191.255.255.255 C 110x 192.0.0.0 223.255.255.255 D 1110 224.0.0.0 239.255.255.255 E 1111 240.0.0.0 255.255.255.255 All Class C addresses, for example, have the leftmost three bits set to '110', but each of the remaining 29 bits may be set to either '0' or '1' independently (as represented by an x in these bit positions):

110xxxxx xxxxxxxx xxxxxxxx xxxxxxxx

Converting the above to dotted decimal notation, it follows that all Class C addresses fall in the range from 192.0.0.0 through 223.255.255.255. IP Address Class E and Limited Broadcast

The IPv4 networking standard defines Class E addresses as reserved, meaning that they should not be used on IP networks. Some research organizations use Class E addresses for experimental purposes. However, nodes that try to use these addresses on the Internet will be unable to communicate properly. A special type of IP address is the limited broadcast address 255.255.255.255. A broadcast involves delivering a message from one sender to many recipients. Senders direct an IP broadcast to 255.255.255.255 to indicate all other nodes on the local network (LAN) should pick up that message. This broadcast is 'limited' in that it does not reach every node on the Internet, only nodes on the LAN.
Technically, IP reserves the entire range of addresses from 255.0.0.0 through 255.255.255.255 for broadcast, and this range should not be considered part of the normal Class E range.
IP Address Class D and Multicast

The IPv4 networking standard defines Class D addresses as reserved for multicast. Multicast is a mechanism for defining groups of nodes and sending IP messages to that group rather than to every node on the LAN (broadcast) or just one other node (unicast). Multicast is mainly used on research networks. As with Class E, Class D addresses should not be used by ordinary nodes on the Internet.
IP Address Class A, Class B, and Class C

Class A, Class B, and Class C are the three classes of addresses used on IP networks in common practice, with three exceptions as explained next.

...hehehe usa ra jud ang clear nga answer based sa article nga imong gi-copy and paste bro. See grey marked below ug mao na imong na answeran ug klaro kaaU.

1. unsa man sad na ang Class A, B, C, and D bro?
2. unsa-on mana nato sila pag-identify and unsa-on man pag-apply?
3. kanus-a na nato sila magamit ang mga Class A, B, C, and D?

@Wire hehehe peace Bro, all your questions was answer not so clearly seguro
ok all questions turns all on IP Addressing :
1st - In classfull addressing ang first part sa IP address is the Network ID ok, and the second part is the host ID kay each part takes up a different amount of numbers depending on the class,ang network ID identifies the network to the outside world.or (Physical IP).nya ang host ID is a specific computer within that network. (Server PC)
these Classes A, B and C ang mga ngallocate to: a large networks nga dunay daghang computers (Class A), mid-sized networks (Class B) and small networks with few computers (Class C). Class D addresses are not divided between network ID and host ID.In addition pa jud Classes A, B and C enable one-to-one communication, while Class D enables one-to-many communication.or Large multi networks.Unya Bro, If the first bit is a zero, the address is Class A have first octets with a decimal number from 1 to 127 e.g 27.x.y.z or
102.x.y.z

Then kung ang ip address starts with "10" it is Class B have first octets with a decimal number from 128 to 191.e.g:
128.x.y.z or
151.x.y.z
and also kung Class C addresses all begin with "110" have first octets with a decimal number from 192 to 223.e.g:
192.x.y.z or
223.x.y.z

Dayun ang Class D addresses begin with "1110."have decimal values from 224 to 239 in the first octet, and the 4 leftmost bits are 1110.e.g:
224.x.y.z
239.x.y.z
Unya last but not the less This leaves Class E with all addresses starting with "1111." IP class E addresses range from 240 to 255 in the first octet, and the 4 leftmost bits are 1111.e.g:
240.x.y.z
255.x.y.z
kani siya tanan maoy system of IP class addresses that been set up to help ensure pagassign og unique IP addresses. DHCP discover, DHCP offer, DHCP request, and DHCP acknowledgment are steps in getting an IP address from a DHCP server.
Lastly Half sa tanang IP addresses under this scheme are Class A addresses, and a quarter of all addresses are Class B, an eighth of all addresses are Class C, and Class D and Class E each have one-sixteenth of all addresses. Class E addresses are reserved for research as far as my knowledge is concern..kani na mga scheme classifies all addresses between 192.0.0.0 and 223.255.255.255 as Class C and all addresses between 224.0.0.0 and 239.255.255.255 as Class D

Sa tanan bag o pa nag start ug networking much better kung obtain lang inyo set-up sa pag configure para dili mo maglibog, kay in the process masipyat mo sa manual ip configuration usahay ma network pero way internet o dili maka access sa internet...pero i am in favor of this quote"mistakes makes the work perfect" if you are kin and interested to learn and become a PRO the net is open and has a massive information for you to learn dig in guys...

...hehehe. ako lang e-rephrase akong mga questions b...

...since, LAN man atong gi-hisgutan karon in general,

1. kanus-a ug asa nato magamit ang Class A Ip Addressing?
2. kanus-a ug asa nato magamit ang Class B Ip Addressing?
3. kanus-a ug asa nato magamit ang Class C Ip Addressing?

...ato lang anam anamon. hehehehe! kana lang sang 3 questions..

@wire Bro,
the answer lays within your self,why? i already explained to you in my previous post,furthermore i will throw back the questions:
1. unsa na network configuration imu gi-plano
2. unsay requirements sa imu giplano na network?
3. is it applicable to the network you are planning?

Ok, Hehehe for the sake of this discussions, to recap your questions:

1. kanus-a ug asa nato magamit ang Class A Ip Addressing?
2. kanus-a ug asa nato magamit ang Class B Ip Addressing?
3. kanus-a ug asa nato magamit ang Class C Ip Addressing?

answer for #1. ang Class A ip addressing bro: These networks consist of 16,777,214 possible IP addresses bout pasabot this is ONLY allocated generally to a large networks such as multi-national companies.

answer for #2. ang Class B ip addressing naman consists of 16,384 individual networks, ug kada allocation nagconsist of 65,534 possible IP addresses kani nga block sa mga IP's allocated oginagamit lamang sa mga? ISP(internet service provider,ug dagkong skwelahan,hospital og goverment offices or installation)

answer for #3. ang Class C ip addressing bro, adunay total nga 2,097,152 Class C networks available, ug kada network gaconsist og 255 individual IP addresses.bout pasabot mao ni ang ato karon ginagamit na mga ip class pang mid-sized o gagmay laang nga network.

Additional pa jud ang Class D-ip addressing mga ip na nakareserve for a service called Multicast.
Unya ang Class E- kini sad na mga ip nakareserve para experimental purposes

so again ikaw ra maka decide what kind of network IP's imu gamiton bro...

The author of this thread was on leave if i'm not wrong. This thread is a great refreshing and very informative to those who are new in Networking. Let ask the the administrator to put this thread to sticky.

I assure its very useful for those who are seeking for knowledge with this thread. Mostly for newbie of Networking procedure.

Thumbs up for this thread. Nice Mr. STRANGER.
