D19-VLSM Subnetting

Today's Packet Tracer lab:

✅ Designed VLSM subnets
✅ Assigned IPs to routers & PCs
✅ Configured static routes
✅ Verified configurations
✅ Achieved end-to-end connectivity

D18: Subnetting practice

Subnetting isn't about memorizing answers-it's about following a process.
✔️ CIDR → Subnet Mask
✔️ Boundary Octet
✔️ Block Size
✔️ Subnet Range
✔️ Network & Broadcast
✔️ First/Last Usable Host

D17- CIDR & Subnetting

✔️ CIDR & prefix notation
✔️ Subnet masks
✔️ Total vs usable hosts
✔️ Number of subnets
✔️ Efficient IP address allocation

Subnetting is one of the most important CCNA skills—every calculation brings me closer to mastering networking.

D16- IPv4 addressing, IP address classes, and CIDR.

🔹 IPv4 address structure
🔹 Class A, B, C, D & E
🔹 Default subnet masks
🔹 Why CIDR replaced classful addressing
🔹 Prefix notation (/24, /26, etc.) and efficient IP allocation

@CyberLoti Thanks! that’s exactly what I followed—routing table first, then interfaces. Still learning tho :)

D15- CCNA Lab: Static Route Troubleshooting

PC1 and PC2 could not communicate, so I began troubleshooting by checking routing tables and interface configurations on each router.

[Himani @HimaniNgr]

@CyberRacheal 127.0.0.1 is called the loopback IP address. When your device sends data to 127.0.0.1, it does not go to the internet or any other device. It comes back to your own machine.

Connectivity Test

Performed end-to-end ping testing.
Initial packets timed out while ARP tables populated.
Subsequent pings were successful, confirming connectivity restoration.

[Himani @HimaniNgr]

Checked R3 configuration.

Discovered an incorrect IP address on the R3

Verification/Fix
Corrected the IP addressing issue and verified the static route configuration.

#CCNA Lab: Static Route Configuration

✅Configured IP addressing
✅Added static routes using "ip route"
✅ erified routes with "show ip route"
✅Observed C(Connected), L(Local) & S(Static) routes
✅Tested end-to-end connectivity
✅Learned next-hop routing & longest prefix match(

[Himani @HimaniNgr]

Day 14- Routing Fundamentals

Today I learned:
🔹 Routing
🔹 Routing Tables (show ip route)
🔹 Connected Routes (C)
🔹 Local Routes (L)
🔹 Route Selection & Longest Prefix Match
🔹 Static vs Dynamic Routing (OSPF)

DNS Server Lab: How devices can access website using domain name instead of IP address.

[Himani @HimaniNgr]

@CyberLoti Thanks! really appreciate the encouragement. I'm trying to focus on understanding the "why" behind the commands, not just memorizing them. More labs coming soon!

D13-#CCNA lab: Switch interface management

✔Verified ports, speed, duplex & VLANs with "show interfaces status"
✔Added interface descriptions
✔Configured "speed 1000" & "duplex full"
✔Used "interface range fa0/3-24"
✔Disabled unused ports
✔Saved configs with "write memory"

7- Max hosts per network:
Formula: 2^h − 2
(h = number of host bits)
Example:
192.168.1.0/24 → 8 host bits
2⁸ − 2 = 254 usable hosts

🧵 Day 12 of learning Networking: IPv4 Addressing Basics

Today I revised IPv4 address classes, loopback addresses, netmasks, and host calculations. 👇

1- IPv4 addresses are 32 bits long and written in dotted-decimal format (e.g., 192.168.1.10).

[Himani @HimaniNgr]

5-Netmask identifies the network & host portions of an IP ad.
Ex:
Class A → 255.0.0.0 (/8)
Class B → 255.255.0.0 (/16)
Class C → 255.255.255.0 (/24)

6-Host rules:
✅ Host bits all 0s =Network address
✅ Host bits all 1s =Broadcast address
❌ Neither can be assigned to devices
