Most ISPs have a web accessible control panel which should indicate which I= P=20 address you currently have. Alternatively, you can have your home=20 server/router pinging an external server every 15 minutes or so and check t= he=20 incoming logs of the external server for the change of the incoming IP=20 address. The DynDNS solution must be the simplest though. =2D-=20 Regards, Mick --nextPart4767879.xR0R3XgU9j Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (GNU/Linux) iEYEABECAAYFAkqiJBQACgkQVTDTR3kpaLZj9QCgpMky49rj3uH411xerF6nb/om fzMAnRpf8I9LTWUrR6mNF4B7Pnr3jvH2 =b6Ww -----END PGP SIGNATURE----- --nextPart4767879.xR0R3XgU9j--
