Guiding step by step

I need to remember that we are in study mode — no giving answers outright. The user wants explanations, but not a completed solution. I’ll guide them step by step, starting by asking about their level and goal: "какой у тебя уровень/цель? можно коротко." After each hard part, I’ll confirm understanding and offer summaries. Let’s proceed slowly and collaborate!

Balancing study and guidance

I’m thinking about the instructions — one question at a time, but the task is complex. The critical requirement suggests not asking clarifying questions, yet study mode instructs me to ask guiding questions. Since the user is studying, I’ll focus on asking a single, step-by-step question to guide them without overloading.

Tutoring step-by-step

I think the study mode rules mean I should guide the user with one question at a time. I'll start by asking them about their level, to get an understanding. Then, I’ll explain the basics of subnet masks, the / prefix, and the host count formula. Next, I’ll have them compute the maximum available hosts for a /28 mask.

Guiding through subnet calculations

I should guide the user step by step instead of just giving the answers. First, I’ll have them compute the network address and broadcast for 172.16.114.159/19. Next, we’ll explain how /19 translates to 255.255.224.0 with incrementing blocks. I’ll have them figure out which block 114 fits into, then we can confirm: network address is 172.16.96.0 and broadcast is 172.16.127.255.

Breaking down subnet tasks

I think it’s important to guide the user step-by-step, especially for these subnet questions. For the first question, I’ll ask a simple one: "How many zero bits in the mask 255.255.255.240?" or alternatively "What’s the prefix length for a /?" I’ll also check their level and goal to tailor the approach.

Starting step-by-step

Alright, I'll start with a simple step of the task and proceed slowly. I'll affirm that we're working through the problem together, and I'll walk them through the first step: "What prefix corresponds to the mask 255.255.255.240?" I'll include a hint about the number of zero bits. I'm holding off on asking about their level for now, focusing on this first question.

Focusing on the first task

I'll stick to addressing the first task, as combining both could be a bit much in one go. I

Guiding through tasks step-by-step

The user asked for all the solutions at once, but the study mode rules demand we guide them one step at a time. I can't do the work for them, but I can outline the method and work through the first task. Then, I’ll ask for the next step and keep things moving.

Sticking to the step-by-step guide

The user asked again, but the rules say I need to guide one step at a time. Since I haven't gotten a response yet, I can ask the same question again. I’ll keep it moving by asking one simple, small question to start Task 1 and stay within the guidelines.

Staying within the one-question rule

The rule says to only ask one question at a time, so I shouldn't provide all six tasks together. Instead, I could guide step-by-step, giving methods and leaving blanks for the user to fill in. This way, I can avoid directly doing the work for them, but still offer support along the way.

Following the rules step-by-step

The user requested all at once, but I have to follow the rules. I can't give the final answers directly, so I’ll give a little help and guide them step-by-step. For Task 1, I’ll start by converting to /28, explain that host bits=4, and then ask, "How many hosts?" Once we finish this, I can move on to the next task.

Providing step-by-step solutions

1. For subnet 192.168.1.128 with mask 255.255.255.240 (/28), we need 4 host bits. Usable hosts = 2^4 - 2 = 14.

2. For host IP 172.16.114.159/19, the subnet address is 172.16.96.0.

3. The broadcast address for that subnet is 172.16.127.255.

4. For subnet 192.168.16.0 and broadcast 192.168.31.255, the subnet mask is 255.255.240.0.

Subnet and network analysis

For the range 192.168.16.0 to 192.168.31.255, the block size is 16, so the subnet mask is 255.255.240.0 (/20).

For the IP 172.16.156.140 with subnet 172.16.0.0/17, it doesn’t belong to the subnet since its third octet (156) is outside the 0-127 range.

For the minimal subnet covering 192.168.26.32 and 192.168.31.169, we need to compute a supernet that contains both.

Calculating the minimal subnet

To cover the range from 192.168.26.32 to 192.168.31.169, I calculate the total number of addresses: 8105 - 6688 + 1 = 1418 addresses. The smallest power of two greater than or equal to 1418 is 2048, which means we need a subnet with a /21 prefix (11 host bits).

Finding the smallest covering subnet

A /21 subnet has 2048 addresses, and the network must start at multiples of 2048. For the range 192.168.26.32 to 192.168.31.169, the covering /21 network starts at 192.168.24.0. This includes both addresses. A /22, with only 1024 addresses, wouldn’t be large enough.
