IP-диапазоны

IP-диапазоны CERNET

Все IPv4 и IPv6 диапазоны, которые CERNET (AS4538) сейчас анонсирует в интернете: CIDR и начальный/конечный IP, бесплатное скачивание в TXT или CSV. Дата среза данных: 2026-11-02.

CERNET анонсирует через AS4538 префиксов IPv4: 3 490 (покрывают адресов: 17 173 248) и префиксов IPv6: 9. Списки ниже это срез от 2026-11-02 из публичной таблицы маршрутизации BGP, отсортированный по адресам и приведённый так, как анонсирован.

О данных об IP-диапазонах CERNET

  • ASN и владельцы

    CERNET анонсирует префиксы из AS4538. Владельцы по данным реестра: AS4538 (ERX-CERNET-BKB - China Education and Research Network Center).

  • Что входит в список

    Диапазоны это префиксы, которые эти ASN анонсируют в публичной таблице маршрутизации BGP (данные получены через RIPEstat), соседние блоки не объединяются. Это не запись о владении адресами: в список могут попасть префиксы клиентов и арендованные адреса, а маршруты, которые видят единицы узлов, могут отсутствовать. Срез от 2026-11-02.

  • Для чего это нужно

    Разрешать или блокировать трафик CERNET в брандмауэре, WAF или nginx, помечать исходные IP в логах по сетям, проверять по совпадению с CIDR, принадлежит ли IP сети CERNET. Помните, что в адресном пространстве облаков и операторов работают и сервисы клиентов, поэтому блокировка всей сети может затронуть посторонние сайты.

Как пользоваться списком IP-диапазонов CERNET

  1. Начните с таблиц выше: отдельно IPv4 и IPv6, в каждой строке CIDR, начальный IP – конечный IP и число адресов.
  2. Нажмите «Скачать TXT» или «Скачать CSV», чтобы получить полный список. В файле все диапазоны: 3 499, а не только первые строки со страницы.
  3. Загрузите TXT одним набором адресов в брандмауэр, роутер или ipset либо вставьте CIDR в правило группы безопасности облака.
  4. Перед боевым использованием проверьте дату среза (2026-11-02). Диапазоны облаков часто меняются, поэтому сверьтесь с официальным файлом диапазонов провайдера.

IP-диапазоны CERNET: частые вопросы

Сколько у CERNET IP-диапазонов?

По состоянию на 2026-11-02 CERNET анонсирует через AS4538 в публичной таблице маршрутизации BGP префиксов IPv4: 3 490 (покрывают адресов: 17 173 248) и префиксов IPv6: 9.

Какой ASN у CERNET?

CERNET использует AS4538. Владельцы по данным реестра: AS4538 (ERX-CERNET-BKB - China Education and Research Network Center). У крупных организаций часто несколько ASN, на этой странице собраны те, что перечислены здесь.

Как использовать список IP-диапазонов CERNET как белый или чёрный список брандмауэра?

Скачайте файл TXT (один CIDR в строке) и загрузите его в ipset, nftables, include с allow или deny в nginx, список адресов роутера или группу безопасности облака. Диапазоны (3 499) лучше загрузить одним набором адресов, а не отдельными правилами. В адресах CERNET работают и сервисы его клиентов, поэтому блокировка всего пространства может отрезать посторонние сайты.

Как часто обновляется список IP-диапазонов CERNET?

Список это срез от 2026-11-02, примерно раз в неделю он заново формируется из публичных данных BGP (RIPEstat). Анонсы меняются каждый день, поэтому перед боевым использованием скачайте список заново, а для облачных провайдеров ещё и сверьтесь с официальным файлом диапазонов.
