Classful Addressing is a DNS and IP Addressing term for the older IPv4 class A, B, and C way of describing address blocks before CIDR became the normal way to express prefixes. 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.
“Classful Addressing showed up like an old textbook and CIDR politely took the marker.”
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.”
DNS is a DNS and IP Addressing term for the Domain Name System, the internet naming system that maps human-readable names to records such as addresses, mail exchangers, aliases, and reverse lookups. 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.
“DNS told the browser where to go, because typing raw IPs all day would make everyone dramatically tired.”
Recursive Resolver is a DNS and IP Addressing term for a DNS server that performs lookups on behalf of clients by asking the DNS hierarchy and caching answers for future requests. 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.
“The recursive resolver did the group project and returned with the answer before the laptop got cranky.”
Authoritative DNS Server is a DNS and IP Addressing term for a DNS server that holds the source answer for a zone and can give final responses for records in that domain. 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.
“The authoritative server had the answer key, while every cache was just borrowing the homework.”
DNSSEC is a DNS and IP Addressing term for DNS Security Extensions, a set of DNS records and validation steps used to prove DNS answers were not tampered with in transit. 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.
“DNSSEC put a seal on the answer so the lookup did not arrive wearing a fake mustache.”
CGNAT is a NAT Traversal and P2P Gaming term for Carrier-Grade NAT, where a service provider translates many customer connections behind shared public IPv4 addresses, often creating problems for inbound and peer-to-peer traffic. 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: RFC 6598 shared address space; RFC 8445 ICE; RFC 1918 private address space.
“CGNAT made the game lobby knock on three doors and still not know which apartment had the controller.”
Carrier Grade NAT is a NAT Traversal and P2P Gaming term for the service-provider deployment pattern for large-scale NAT used during IPv4 exhaustion, commonly associated with shared address space and NAT444 designs. 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: RFC 6598 shared address space; RFC 8445 ICE; RFC 1918 private address space.
“Carrier Grade NAT saved addresses, then the multiplayer match asked why every player looked like the same house.”
RFC 6598 is a NAT Traversal and P2P Gaming term for the IETF RFC that reserves 100.64.0.0/10 as shared address space for service provider networks using Carrier-Grade NAT. 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: RFC 6598 shared address space; RFC 8445 ICE; RFC 1918 private address space.
“RFC 6598 gave providers 100.64/10 so CGN boxes would stop borrowing the furniture from private networks.”
100.64/10 is a NAT Traversal and P2P Gaming term for the shared IPv4 address block from 100.64.0.0 through 100.127.255.255, reserved for use between customer equipment and provider CGN devices. 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: RFC 6598 shared address space; RFC 8445 ICE; RFC 1918 private address space.
“100.64/10 was the hallway between the home router and the carrier NAT, not a public front porch.”
