Preface Originally, I didn't really want to write this article, because fundamentally speaking, concepts like "Custom IP", "Preferred IP", and "Preferred Domain" are not official terms. To put it nicely, they are "folk remedies"; to put it bluntly, they are "heretical paths" (as the Old Kai would say). I also specifically mentioned this in my previous articles...

Preface Since I officially published my first article on August 25th last year (the one on August 7th was just a test), it has been almost exactly one year. During this year, I don't even remember how much piecemeal knowledge I learned to tinker with this blog, or how many bottomless pits I stepped into. Today, although it barely counts as...

Preface With the official conclusion of the ten-part Cloudflare tutorial series (these ten parts are considered the main series; if more are released in the future, they can only be considered spin-offs, which doesn't affect the fact that the main series has only ten parts~), I figured I should open a separate summary post for Cloudflare: which will include the tutorial series and...

Preface Actually, I originally wanted to end the CF tutorial series at the ninth part, "Zero Trust". After all, in the I Ching, nine is called the “great number”, representing the largest and most complete number between heaven and earth, as in the Nine Heavens, nine-nine returning to one, the eighty-one (nine times nine) tribulations, and so on. Therefore...

Preface: Actually, CF Zero Trust was originally a feature set that I valued highly and prepared to introduce in great detail. After all, it can provide comprehensive security protection for enterprises, plus its important component warp+ (originally using warp to associate with one's own Zero Tru...

Preface: Among the many features of CF, there is a very practical feature that I only learned about in recent months, which is the protagonist of this article: R2 (the object storage service provided by CF). Through R2, it can meet an important need that personal webmasters have to face in the early stages of building a website: image hosting. Additional knowledge:...

Preface: The 7th part of the CF tutorial series, the time to write the CF Worker tutorial is finally ripe. Why do I say this? The reason why I left CF Worker to be written later is because "to make a certain type of traffic eventually accepted and processed by the corresponding worker, the prerequisite is that the traffic...

Preface: In the completed CF tutorial series "1" to "5", in addition to the foundation-building trilogy of "1" to "3", in the subsequent "4" and "5", I introduced CF WAF and CF DDoS protection respectively, because I believe these two features are the two most valuable in the CF traffic sequence...

Preface: Among the many features provided for free by CF, besides WAF, the DDoS protection feature is the most practical. Even from some perspectives, DDoS protection is the most practical feature provided for free by CF (mainly for those in China who suffer from DDoS attacks consuming their purchased cloud resources...

Preface: After completing the "foundation-building" trilogy of the Cloudflare tutorial series (CF overall solution, traffic sequence, edge network, and origin pull), the CF tutorial series is finally going to start introducing specific features and configurations. So, which feature should be chosen first? After much thought...
