How this service works
Is TCP port 548 (AFP) open on a host? Attempts a connection from Cloudflare's edge and reports open/closed/filtered with the connect time; Cloudflare-fronted hosts are reported as inconclusive because their edge answers for them. Exposure checks for AFP without running a scanner. $0.01 per check.
Output
Returns the port status (open, closed, or filtered) for TCP port 548 on the target host, including the TCP connect time in milliseconds. If the host is behind Cloudflare, the result is flagged as inconclusive because Cloudflare's edge may answer the connection on behalf of the origin server.
Example use cases
AFP exposure audit on production server
“Can you check whether port 548 is open on my server at 198.51.100.10? I want to know if the Apple Filing Protocol is accidentally exposed to the internet.”
Security scan before server decommission
“Before we decommission the old file server at nas.mycompany.example.com, can you verify whether TCP port 548 is still open and reachable from the outside?”
Client network compliance check
“I need to confirm that AFP (port 548) is not publicly accessible on the host 192.0.2.77 — can you probe it and tell me whether it shows as open, closed, or filtered?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/port/548?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, passive check of AFP (TCP port 548) exposure on a specific host without deploying a full port scanner. It is ideal for security audits, compliance checks, or pre-deployment validation where you want an external perspective from Cloudflare's edge network. Prefer it over generic port scanners when you specifically need AFP detection and want a lightweight, pay-per-use API call at $0.01 per check.
Side effects
- Host is Cloudflare-fronted — result returned as inconclusive rather than true open/closed
- Host is unreachable or DNS does not resolve — likely returns filtered or error
- Firewall silently drops packets — port reported as filtered rather than closed
- Connection timeout if host is very slow to respond
- Invalid or private IP address provided — may return error or filtered status
