About DBpedia

The AMPRNet (AMateur Packet Radio Network) or Network 44 is used in amateur radio for packet radio and digital communications between computer networks managed by amateur radio operators. Like other amateur radio frequency allocations, an IP range of 44.0.0.0/8 was provided in 1981 for Amateur Radio Digital Communications (a generic term) and self-administered by radio amateurs. In 2001, undocumented and dual-use of 44.0.0.0/8 as an internet telescope began, recording the spread of the Code Red II worm in July 2001. In mid-2019, part of IPv4 range was sold off for conventional use, due to IPv4 address exhaustion.

dbo:abstract HAMNET (Highspeed Amateurradio Multimedia NETwork,. Eigenschreibweise HAMNET) ist ein von Funkamateuren entwickeltes und betriebenes funk- und kabelbasierendes IP-Netzwerk. Es dient als leistungsfähiges Backbone für die bereits verfügbare Infrastruktur des Amateurfunkdienstes und ermöglicht IP-Anwendungen. HAMNET war als sukzessive Substitution des seit den 1980er Jahren bestehenden Packet-Radio-Netzes intendiert und hat dieses fast vollständig abgelöst. Die Datenverbindungen zwischen den Einstiegspunkten werden über das 6 cm, 9 cm und 13 cm Band abgewickelt. Über das Netzwerk werden eine Reihe weiterer Amateufunkdienste wie EchoLink, WinLink2000, Instant Messaging, VoIP, DATV/ IP ATV und APRS abgewickelt.

(en) AMPRNet (AMateur Packet Radio Network) / Hamnet (ham network) est un réseau de type IP mis en place par des radioamateurs pour l'utilisation de services IP (telles que les liaisons packet radio dans les années 1990). En raison de la forme des adresses IP qui y sont utilisées, on parle également de réseau 44/8 ou réseau 44. AMPRNet/Hamnet est donc un réseau de même nature qu'Internet ; par conséquent il est possible d'y utiliser les services habituels de ce dernier : world wide web, FTP, ping, etc. Jusqu'au début des années 2000, les liaisons (en VHF et UHF) étaient le plus souvent limitées à 9600, 1200, voire 300 bit/s. Cependant, le réseau connaît actuellement un renouveau fondé sur l'utilisation des protocoles de la famille IEEE 802.11 (« wifi »), ce qui autorise des liaisons haut débit à plusieurs mégabits par seconde. (fr) AMPRNet (сокр. от англ. AMateur Packet Radio Network) — компьютерная сеть, соединённая посредством любительских радиостанций. По-другому сеть называется IPv4 Network 44/8 или просто сеть 44. AMPRNet соединена точками доступа через любительское пакетное радио. Скорость связи обычно не превышает 9600 бод (часто 1200 и меньше) из-за ограничений пропускной способности радиоэфира. AMPRNet полностью поддерживает TCP/IP, что позволяет использовать протоколы FTP, Telnet, Ping, Finger и HTTP. Недавно AMPRNet появилась возможность устанавливать связь между точками доступа на скорости 108 Mbps благодаря использованию (HSMM). На сегодняшний день AMPRNet состоит из нескольких подсетей, расположенных по всему миру. Многие подсети соединены туннелями через Интернет. (ru) AMPRNet (AMateur Packet Radio Network) – zbudowana przez krótkofalowców amatorska sieć komputerowa połączona z radiostacjami. Inne nazwy tej sieci to IPv4 Network 44/8 i Network 44. Krótkofalarstwo używało już protokołu TCP/IP w sieci Packet Radio długo przed pojawieniem się publicznego internetu. Klasa A 44 posiada zarezerwowane ponad 16,7 milionów adresów IP przeznaczonych dla radioamatorów na całym świecie, nastąpiło to w latach siedemdziesiątych dzięki staraniom , kiedy internet był jeszcze w powijakach. AMPRNet jest związany łączami (linkami) z siecią Packet Radio. Z powodu ograniczeń szerokości pasma radiowego, linki zwykle ograniczone są do maksimum 9600 bodów, najczęściej 1200 bd na VHF i UHF oraz 300 bd na KF. AMPRNet w pełni obsługuje TCP/IP uwzględniając obsługę protokołów FTP, Telnet, Ping, Finger i HTTP. Ostatnio AMPRNet zyskał szybkość połączenia radiowego do 108 Mbit/s używając protokołu . Adresy IP w tym bloku (A 44) zawierają się w przedziale 44.0.0.0/8 i są dostępne dla każdego licencjonowanego krótkofalowca. Adresy przypisywane są przez koordynatorów wolontariuszy i są routowane przez internet. Koordynatorem polskiej sieci AMPRNet od 03.2013 roku jest Janusz Przybylski (Szczecin). Sieć AMPRNet używa domen drugiego poziomu ampr.org, które dostępne są dla krótkofalowców chcących zarejestrować i uruchomić swoje hosty lub do innych celów związanych z amatorskimi systemami komputerowymi. (pl) AMPRNet, en förkortning av Amateur Packet Radio Network, är ett TCP/IP-baserat nätverk för radioamatörer. Under 1970-talet lyckades KA6M, Hank Magnuski, registrera hela 44-nätet för amatörradiobruk. Detta ger radioamatörer runt om i världen över 16 miljoner IP-nummer för bruk i AMPRNet. Hälften av dessa IP-adresser har reserverats för amerikanska radioamatörer. Svenska radioamatörer har allokerats ett IPv4-subnät av B-klass, närmare bestämt 44.140.0.0/16 (vilket ger 216 = 65536 unika adresser). Stöd för IPv6 är på väg. Nätet administreras idag av ett stort antal lokala radioamatörer.
