TelegramBot (link preview)

Fully verifiable

Telegram's fetcher for generating link previews in chats. Telegram publishes the network ranges its infrastructure uses as a plain-text list on its own documentation host, which is what attributes a request to Telegram; the separate webhook guide documents only the two subnets used for inbound webhook delivery to bot servers.
