An independent Linux alternative inspired by PowerToys Hosts File Editor for inspecting, editing, validating, testing, and organizing /etc/hosts entries and named host profiles on Linux desktops and workstations.

Key Features:

• Real System /etc/hosts Parser: Reads /etc/hosts directly from the Linux host filesystem, distinguishing active mappings, commented-out disabled mappings, and preserved header comments.
• Structured Table Editor & Validator: Edit IP addresses, primary hostnames, aliases, comments, and enabled toggles with instant IPv4/IPv6 syntax checks (Python ipaddress), RFC hostname validation, and duplicate conflict alerts.
• Live DNS Resolution & Socket Latency Tester: Measure real getaddrinfo DNS resolution results, address families, and TCP socket connection latency (ms) alongside live /etc/resolv.conf nameserver inspection.
• Named Profile Manager: Save, load, compare, and switch named hosts profiles stored in the user configuration directory, and export clean hosts files, CSV/JSON reports, or ready-to-run sudo cp apply commands.
• Bilingual Interface: Switch instantly between Vietnamese and English.
