SPF2IP

✓ from SPF2IP import SPF2IP

✗ from spf2ip import get_ip_addresses

Retrieve all IP addresses authorized by the SPF record for a domain.

from spf2ip import get_ip_addresses ips = get_ip_addresses('example.com') print(ips) # Output: {'192.0.2.1', '198.51.100.1', '2001:db8::1'}

Debug

Known issues

gotchaThe function returns a set, not a list. May cause confusion if you expect ordered results.

fix

Use sorted(ips) or list(ips) if order is needed.

affects: all

gotchaDNS lookups can be slow or fail; ensure network connectivity or handle exceptions.

fix

Wrap call in try-except for spf2ip.exceptions.DNSError or general Exception.

affects: all

gotchaSPF records with includes/macros are resolved, but recursion depth is limited; very complex SPF records may return incomplete results.

fix

Manually verify against authoritative SPF for large domains.
