You must never make assumptions about what fits in one packet. The MTU could be 100, or less, or 8000, or more.
As soon as you start doing math based on MTU values that you don't permanently have end-to-end control of yourself, you're setting yourself up for trouble.
- oofabz 11y agoThat's true, it's a bad idea to assume an MTU of 1500. Although there is no minimum MTU in IPv4, IPv6 specifies a minimum of 1280 bytes. So if you send your UDP packets over IPv6, you are guaranteed room for 1232 bytes of payload.
