prefixkit Telegram bot

Network and telephony checks right in Telegram: who owns an IP, DNS records, whether a port is open, whether a SIP server answers, MAC vendor, SIP codes and questions to an AI engineer. Free.

The bot is launching; the link will appear here shortly.

No command needed: send an IP, a domain, a MAC address, a SIP code or just a question.

Why a bot

When you are at the rack with a phone and the laptop is far away, checking a port, DNS or a SIP server is faster in a messenger. The bot uses the same checks as the site: TCP and SIP from Cloudflare servers, ping through Globalping probes.

Limits

Up to 12 commands a minute, 30 pings and 10 AI questions a day per chat. The bot does not store conversations.
