An AS-SET is a collection of Autonomous System Numbers grouped under a single name. Rather than listing each ASN individually in your routing policy, you just refer to the set, and the routing registry handles the details. You can think of it like a mailing list for networks.
Wireless signal fade happens when the radio signal drops in strength or quality. Distance, weather, interference, and physical obstructions all play a role. Even small changes matter. Water absorbs RF energy. Heat bends signals. Trees grow. The result is lower signal-to-noise ratio, higher error rates, and retries that pile up fast
Companies love email. It is cheap, fast, and easy to send at scale. That ease creates a quiet risk. When everything is “important,” nothing is. This is like the modern version of crying wolf.
Welcome to the first Packets Down Range of 2026. Lots of things happening in the world on The Capital I Internet. So grab your multi-tool, fire up your terminal, and let’s head down range.
An ultrasonic beacon is a short audio signal. It lives above normal hearing, often above 18 kHz. Speakers in TVs, kiosks, or stores can play it. To you, it sounds like silence.

We like to think communication is simple. Someone talks. We hear the words. Message received.
Anyone who has worked on a team, managed a business, or solved problems with others knows it’s not that simple.
Many Internet service providers believe PeeringDB is just for networks in large data centers. That belief sticks around like an old patch cable at the bottom of a toolbox. The reality is simpler: every ISP should have a PeeringDB entry, even if you never set foot in a carrier hotel, IXP, or meet-me room. Your … Read more
