Default Gateway Compatiblity - .0 or .1

Overview

While both .0 and .1 endings for default gateway addresses are technically possible, there are compatibility and convention considerations that affect their usage.

Technical Details

  • .0 - Traditionally reserved for network address
  • .1 - Commonly used for default gateway/router
  • .255 - Reserved for broadcast address

Compatibility Issues

MacOS and WebOS have known compatibility issues with default gateways ending in .0, while Android and server applications generally work with either address[1].

Best Practice

Using .1 as the default gateway address is recommended because:

  1. It follows historical networking conventions[2]
  2. It provides better cross-platform compatibility[1]
  3. It avoids potential issues with legacy systems that might reserve .0 for network addressing[3]
  1. Based on observed MacOS and WebOS behavior

So I was watching kitze's latest video on why you shouldn't build in public maybe on Safari and my Airpods Pro 2 make the same stuttering / chopping sound with the audio and video falling out of sync, as it always has, every so often. The behaviour repeats consistently.

If you use docker-compose (like you should), the MTU is still going to be the default of 1500 because every docker compose file is treated as a separate set of services that warrant a separate network.

Since humankind evolved, one question has persisted: to obsidian or to obsidian with other tools in parallel. This note tries to balance out the equation by throwing in some personal observations and pointers, which are supposed to help me tilt the balance for a while, at least.
