All too often we take this protocol for granted.<\/p>\n

Sure signposts in a field works just fine – but it pays to understand a little more about what is going on here.<\/p>\n

A colleague (Alex) saw this on Imgur (alas without credit… and now without all the comments) – and it seemed far, FAR too good not to share.<\/p>\n

Be gone smoke and mirrors – here we have a 101 on DNS.<\/p>\n

Worthy of note you will often hear us talk about propagation delay – this is the bit where the DNS server says “Okay, I will save that for a while”. It stamps it with a Best Before Date (which is dictated by the TTL – Time To Live – on that record), and will continue to use that record until that point is reached – at which point it will fetch another.<\/p>\n

Thank you unnamed artist!<\/p>\n
