Based on my last post on VLSM that did well, today I am going to touch on CIDR Block aggregation.

CIDR - Classless Inter-domain routing, this is the method for allocating IP addresses, showing in the / notation.

Let’s take an example: You mange for different subnets for different departments:

1. 192.168.1.0 with /24
2. 192.168.2.0 with /24
3. 192.168.3.0 with /24
4. 192.168.4.0 with /24

Question: What single CIDR block can we summarize all four IP addresses above?

Solution:
Take the starting (smallest IP block) and the ending (largest IP block):

Which in our case are:
192.168.1.0
192.168.4.0

Next up:
We just convert this IP into binary, knowing the power of 2 rule from right to left, when we convert the starting and ending IP Address we get the following:

Starting IP - 192.168.1.0:
192 in binary: 11000000
168: 10101000
1: 00000001
0: 00000000

Ending IP - 192.168.4.0:
192 in binary: 11000000
168: 10101000
4: 00000100
0: 00000000

Now that we have convert both the starting and ending IPs into binary, we see where the bit changed for the network portion (the network portion is the left side of the octet and the host portion is the right side of the octet)

192.168 were same, the bit changed in the 3rd octet, on bit no. 22, so the first 21 bits were identical for both starting and ending IP address.

Therefore the change happened in the 3rd octet, therefore the network portion that remain unchanged are the 1st and 2nd octet.

Answer: 192.168.0.0 with /21 aggregates the above blocks.

FixMySEO is a SAAS that scans domain looking for SEO related issues, and give CMS specific introductions on how to fix those issues, additionally also validate those fixes as well.

So, you don’t scan and get a huge report of all SEO related issues, rather you scan —> get step by step instructions to fix them —> validate fixes

Try it out scanning your site domain today, will leave out a link in the comments section.

3 months into my very first SAAS and I’ve learned something I probably should have understood before writing the first line of code.

Building the thing is the easy part.

I spent weeks on working scanner logic, scan limits, scoring system, validation, database behavior, PDF exports and all others.

Then I launched my SAAS

And suddenly the question changed from “How do I build this?” To “Why would anyone use this?”

My SAAS FixMySEO is an SEO scanners that doesn’t stop at reporting problems, it also provides CMS specific fixing instructions and lets you validate the fix.

The product keeps getting better, but getting distribution well that’s the real challenge.

For anyone else bidding a micro-SaaS right now, what has been hard for you, product or distribution part.

I have a PC with RTX 2060 but it’s actually an AMD built, though there is no issue with the current RTX 2060, but I can’t game for more than 60fps, so I have decided to go with either the RX 9070XT or the 9060XT brand doesn’t matter, but yes this model matters, so if anyone is selling their graphics card let me know. Ofcourse looking for a reasonable pricing and preferred location in UAQ, Ajman, Sharjah or Dubai.

Also I checked Dubizzle but didn’t find anything good there.

One feature in my SEO SaaS took me longer to get right than I expected.

Validate Fix.

Most SEO scanners basically work like this:

1. Scan website
2. Find issue
3. Show issue
4. Done.

But then what?

You fix the missing meta description.

You change the title.

You add the canonical.

Then you have to trust that you've actually fixed what the tool found.

I didn't like that.

So I built FixMySEO so that after fixing an issue, you can run validation and have the scanner check the page again.

The SEO score recalculates when the issue is successfully resolved too.

As this became the core feature of FixMySEO

Because an SEO audit shouldn't end with:

“Here are 18 things wrong.”

It should end with:

“Here are 18 things wrong, and let's confirm they're actually fixed.”

That’s the direction I’m taking the product in.

So here are some of my absolute favorite reads so far in 2026 (without any specific order):

1. Can’t Hurt Me by David Goggins
2. Richard Branson Biography
3. 13 Reasons Why?
4. The Mountain is you
5. Road to Success by Napoleon Hill
6. Quicksilver - Novel

Let me know your favorite reads of 2026 so far, in the comments section.

So I have been thinking about starting a Pokémon cards collection, but don’t know where to start with, since I am a complete beginner, are there any people that collects Pokemon Cards here in the UAE.

I am trying to collect rare and graded collection of the cards, if you are someone who has done/have been doing it, could you guide me on this.

So it’s been 2 months since my first ever SAAS went live.

FixMySEO:
Scan your domain for SEO related issues and get step by step fixes for each of the issue(s).

A little backstory:
I have been doing SEO on my sites and client sites for the past 2 years, one thing I have struggled the most with is relating to SEO issues that I was completely unaware of, so I decided to build a SAAS that exactly does this, if finds issues such as Broken Links, Too many links on page, Missing Canonical Tag, Missing Meta-Description, Missing H1 Tags and more those issues that I was likely to miss out.

This isn’t just about scanning out your domain and give you a list of issues per page, rather it gives you step by step fixes for each of those issues if found, those steps are also not generic, meaning it detects the website builder like WordPress, Shopify, etc. and provides fixes on that basis.

So, not because I have made it, but I am very confident that it can help everyone who mostly overlook these issues.

This is a post on Variable Length Subnet Mask (VLSM).

What is VLSM?
Instead of fixed length subnet mask like /8, /16, /24 we move out of it by using variable of subnet mask like /9, /10, /22, etc.

With that being said, let’s take a scenario:
You’ve been assigned the ip block of 192.168.10.0 with /24 and need to allocate for the following:
IT Department: 50 hosts
HR Department: 20 hosts
Management: 10 hosts
Guest Network: 5 hosts

Step by step guide on this

Step 1: Sort by host requirements from largest to smallest
IT - 50
HR - 20
Management - 10
Guest - 5

Step 2: start with the largest subnet first:
IT: needs 50 hosts
Using the power of 2 = 2^6 =64
How many bits we used to get the requirement 64 hosts, 6 bits.
So from the Octet, we have Network portion (left) and then the host portion (right).
192.168.10.0 - each number is considered 1 Octet, containing 8bits, since we began with /24 meaning the 3 octets are for the network portion, and the last octet with remaining 8 bits, that’s where will assign the host portion, since we need 50 hosts for the IT Department.
Since require 6 bits for the host portion of the last (4th of octet ), leaving 2 bits for the network portion, so from /24 we add 2 more for the network portion, therefore the new subnet mask is /26
To allocate the ip block to this It Department, since we used the power of 2 which is 64 ip addresses in each block, note: the first one and the last one are not usable, therefore giving us 62 available ip addresses, hence matching our 50 hosts requirement.
The Usable Range: 192.168.10.1 - 192.168.10.62
First Usable IP address: 192.168.10.0
Last usable IP address: 192.168.10.63
Next IP block begins with 192.168.10.64

Step 3: similarly like Step 2 we allocate the IP addresses for the next largest host requirement
HR: Needs 20 hosts
Closest to the power of 2 to get 20 hosts, 2^5‎ = 32
Meaning 5 bits goes to the host portion in the last octet
The new subnet mask becomes /24 to /27
Next available block: 192.168.10.64 /27
Usable range: 192.168.10.65 - 192.168.10.94
Broadcast: 192.168.10.95

Step 4:
Management: needs 10 hosts
Closet to the power of 2 to get 10 hosts is 2^4=16
Meaning 4 bits goes to the host portion from the last octet
The new subset mask is /28
Next available block: 192.168.10.96 /28
Usable range: 192.168.10.97 - .110
Broadcast: 192.168.10.111

Step 5:
Guest: needs 5 hosts
Closest to the power of 2 to get 5 is 2^3=8
Meaning 3 bits goes to the host portion from the last octet.
The new subnet mask is /29
Next available block: 192.168.10.112 /29
Usable range: 192.168.10.113 - .118
Broadcast: 192.168.10.119

I made a recent post about asking you, what’s one thing you’ve been struggling the most with and it was this VLSM, I hope this has been helpful, if you have any question on the above, let me know in the comments section down below.

It’s Friday yet another post on Guess the book by its brief description.

How it works?
I will write a brief description of a book, and you guys comment in the section down below, the correct one to guess the book title will be pinned in the comment sections.

Here’s the book brief description:
Cosmic journey through space and time to rescue a missing scientist father from an evil planetary force.

Hint:
The book title starts with “W”

I have started a few months back about designing few web templates for every type of business, the goal is to make it easily available to everyone on the net.

3. ⁠Dental Clinics
4. ⁠Fashion Stores
5. ⁠Gym and Fitness Centre
6. ⁠Online Courses
7. ⁠Real Estate
8. ⁠Restaurants and cafes
9. ⁠Schools and Nurseries
10. ⁠Web3

If you have read so far, and have any specific website requirement of yours, leave it out on the comments, will try my best to design a template for it.

So over the past few months I have been making out a few website templates for the following industries.

1. Beaty Salon

3. Dental Clinics
4. Fashion Stores
5. Gym and Fitness Centre
6. Online Courses

The goal is to make these templates easily accessible to whoever so needs it.

I will add a link to the website down below.

So it’s been more than a year now since I am looking out for a job here in the UAE.

Tried looking jobs on LinkedIn, Indeed Jobs, reached out to companies hiring via email and even did the walk-ins.

Still no luck, I am cursed or something, don’t know where/what I am doing wrong?

Little background about me, graduate in IT/ Networking with CCNA and Microsoft Azure certifications, 4 years of UAE experience as IT Engineer:

I have also updated my CV recently to match the current job market as well. Available to join immediately.

If you’re someone who’s hiring/knows someone hiring, kindly refer me.
