Some things in RFC1925, despite it being one of a series of April Fools’ RFCs (and therefore in the good company of the all time classic RFC1149 and it’s brethren), actually do hold true, for instance:
Fast, Good, Cheap: Pick any two – still tends to hold true.
However, like all good April Fools’ RFCs, it will declare that ‘ERRATA EXIST’ at the top. In this case, there’s definitely a shred of truth to this. Especially when you look at truth number 4:
Some things in life can never be fully appreciated nor understood unless experienced firsthand. Some things in networking can never be fully understood by someone who neither builds commercial networking equipment nor runs an operational network.
My concern is that this statement no longer holds true for the makers of commercial networking equipment.
If the makers and protocol designers really understood, we wouldn’t be pushing water up hill with things such as IPv6 deployment and encouraging use of other networking best practices, they would have made them easier to deploy in the first place.
Therefore a correction is needed, “Some things in networking can never be fully understood by someone who doesn’t run an operational network“.
