PacketbrewNetwork Architectures That You Need to Know
Network Architectures That You Need to Know Your home Wi-Fi, your company’s office network, and the data centers behind services like Netflix all run on the same handful of proven architectural patterns. Get the architecture wrong, and you end up with bottlenecks and outages. Get it right, and the network just works.
Routing Table and Best Path Selection
Routing Table and Best Path Selection If you’ve ever looked at a routing table and wondered why one route was chosen over another, you’re not alone. Routers often have multiple ways to reach the same destination — but they never just “pick one.” There’s a strict, predictable process behind every decision.
Packet Walk - The Secret Journey Every Web Request Takes
Packet Walk: The Secret Journey Every Web Request Takes Have you ever wondered what actually happens to your data as it travels across a network? Every packet is wrapped in multiple headers, but most of that information stays consistent from source to destination. The two things that do change along the way are the IP addresses and the MAC addresses.
Why the Internet Ran Out of Addresses — And Whats Fixing It
Why the Internet Ran Out of Addresses — And What’s Fixing It A beginner-friendly guide to IPv4, IPv6, and the biggest upgrade in internet history.
Every device connected to the internet — your phone, your laptop, your smart TV — needs a unique address so data knows where to go. Without it, the internet simply doesn’t work. That addressing system is called an IP address, and right now, the internet is in the middle of a massive, decades-long migration from one version to another.
Default Gateway vs Default Route - Whats the Difference
Default Gateway vs Default Route — What’s the Difference? You type packetbrew.com into your browser. Your computer resolves it to an IP address. Now it has to answer one simple question:
Is this destination on my network — or somewhere else?
If the answer is “somewhere else,” two things kick in to get your data where it needs to go: the default gateway on your device, and the default route on your router. They’re closely related, often confused, and together they’re responsible for getting virtually every packet off your network.
