Understanding localhost and 127.0.0.1: Differences, Similarities, and IPv6 ::1

localhost is a local hostname that resolves to the loopback IP address 127.0.0.1, while 127.0.0.1 is the IPv4 loopback address itself; both serve the same purpose, with differences in resolution and configuration, and in IPv6 the equivalent hostname maps to ::1.

Understanding Loopback Addresses, Ping, and Why 127.0.0.1 Works Offline

The IPv4 loopback address 127.0.0.1 (also reachable via the hostname localhost) is reserved for internal communication, so pinging it never leaves the host and works even with the network cable unplugged, while 0.0.0.0 is an unspecified address used only for binding to all interfaces and cannot be pinged.

Investigation and Optimization of Unexpected AAAA DNS Requests in Go Applications

The article investigates why Go applications unexpectedly send AAAA DNS queries to a secondary nameserver, tracing the issue to the built‑in resolver’s handling of non‑recursive responses from a NetScaler proxy, and recommends using the cgo resolver, enabling recursion, or forcing IPv4 to eliminate the added latency.
