CIDR 是 DNS 和 IP 地址 术语，用来说明 Classless Inter-Domain Routing notation, such as /8 or /24, used to describe the network prefix length of an IP block。它帮助人和代理明确这个信号、来源和安全的下一步，不把自动化、营销活动、DNS、RFC 或网络路径说成超过证据的样子。来源: IETF DNS technology; RFC 1918 private address space; RFC 6598 shared address space。
“团队在发布前用了 CIDR，这样自动化就不会像书包拉链没拉好一样一路掉东西。”
CIDR is a DNS and IP Addressing term for Classless Inter-Domain Routing notation, such as /8 or /24, used to describe the network prefix length of an IP block. It helps people and agents name the signal, source, and safe next step without pretending an automation, campaign, DNS record, RFC, or network path did more than the evidence shows. Source context: IETF DNS technology; RFC 1918 private address space; RFC 6598 shared address space.
“CIDR made the subnet fit on one sticky note instead of three confusing paragraphs.”
