Konta Subnetting hanesan dalan ida nebe ema uja ho objektivu atu halo kiik rede komputador nebe iha. Basikamente, subnetting uja para atu buka hatene : Numero Subnet, Numero Host per Subnet, Blok Subnet, nomos morada Host Broadcast.
IP Address geralmente hakerek hanesan ne’e: 192.168.1.2. Maibe dalaruma mos hakarek hanesan ne’e: 192.168.1.2/24. Ida ne’e signifika katak IP Address 192.168.1.2 ho subnet mask 255.255.255.0. Numero /24 katak, 24 bit subnet mask nebe haleu husi numero binari 1. Iha dalan seluk bele dehan katak, nia subnet mask mak: 11111111.11111111.11111111.00000000 (255.255.255.0). Konseptu ida ne’e mak bain – bain ema hanaran: CIDR ( Classless Inter-Domain Routing ) (1992 husi IEFT).
Subnet Mask iha tabela kraik ne’e hatudu mai ita katak, subnetting nebe mak desidi ona konta husi Class A ate Class C. Iha lisaun ida ne’e classe D ate E sei la inklui.
| Subnet Mask | Valor CIDR | Subnet Mask | Valor CIDR |
| 255.0.0.0 | /8 | 255.255.240.0 | /20 |

SUBNETTING BA IP ADDRESS CLASSE C
Oinsa atu halo konta ba subnetting ho NETWORK ADDRESS 192.168.1.0/26?
Analija: 192.168.1.0 signifika katak classe C ho nia Subnet Mask /26 signifika katak 11111111.11111111.11111111.11000000 (255.255.255.192).
Modu Konta:
Uluk nanain ita halo nia sistema hanesan tuir mai ne’e:
1.Numero Subnet = , x = binari 1 iha oktet ikus subnet mask . Entaun numero Subnet mak = 4 subnet.
2. Numero Host per Subnet = - 2, y = binari 0 iha oktet ikus subnet. Entaun numero host per subnet mak - 2 =62 host.
3. Blok Subnet = 256 - 192 (valor oktet ikus subnet mask) = 64. Subnet tuir tan mai mak hanesan 64 + 64 = 128, i 128 + 64 = 192. Entaun total subnet mask mak 0, 64, 128, 192.
4. Host no Broadcast nebe valido hanesan notas deit katak, host primeiro mak numero 1 depois de subnet, i broadcast mak numero 1 antes subnet tuir mai. Exemplo:
| Subnet | 192.168.1.0 | 192.168.1.64 | 192.168.1.128 | 192.168.1.192 |
| Host Primeiro | 192.168.1.1 | 192.168.1.65 | 192.168.1.129 | 192.168.1.193 |
| Host Ikus | 192.168.1.62 | 192.168.1.126 | 192.168.1.190 | 192.168.1.254 |
| Broadcast | 192.168.1.63 | 192.168.1.127 | 192.168.1.191 | 192.168.1.255 |
Subnet mask nebe mak uja atu halo subnetting class C mak hanesan tuir mai ne’e::
| Subnet Mask | Valor CIDR |
| 255.255.255.0 | /24 |
| 255.255.255.128 | /25 |
| 255.255.255.192 | /26 |
| 255.255.255.224 | /27 |
| 255.255.255.240 | /28 |
| 255.255.255.248 | /29 |
| 255.255.255.252 | /30 |
Iha mos dalan oinsa atu halo konta ba subnetting classe A nomos B. Maibe konta ba subnetting ne’e ami sei fo sai iha ami nia posting tuir mai. Ikus mai ami hato’o obrigado ba ita boot sira nebe mak hola tempo atu visita ami nia blog ne’e.
Ba kolega sira nebe mak baruk atu le'e karik, entaun bele download deit nia e-book iha ne'e(klik imagem ne'e atu hahu download:
