Veering off this topic's course, Is there any issue with addresses like this ? 2001:470:1f00:1aa:abad:babe:8:beef < I have a bunch of these type 'addresses' configured for my various machines.
I make it a point to come up with some sort of 'hex' speak address, what are peoples opinions on this?
I tell my students to avoid them. For several reasons: - if you need to remember an IP address, you are doing it wrong - limiting yourself to "word space" wastes "address space". Possibly acceptable in interface IDs, foolish in subnetting bits. - if people expect something, they will type it, possibly instead of what's actually needed. By making them expect words, you introduce a source of error. - cultural sensitivity and plain good sense suggest that many words or combinations might not be a good idea. How do your female techs feel about "BAD:BABE"? Only marginally better than they feel about "B16:B00B:EEZ", probably. Your markets in India, with its 900 million Hindus, might take a dim view of "DEAD:BEEF". Etc. - clever addresses are guessable addresses for scanners, and highly identifiable in data as probably attached to high-value targets - something that is witty once is generally irritating the thousandth time you see it. Doubly so if it wasn't very funny to begin with. - the time you spend trying to find something "meaningful" is basically wasted, and the time you spend will increase exponentially once you've used all the low-hanging fruit. All in all, using such addresses is probably a Bad Idea.
