[Cluster-tech] PC92 A

[Dirk Koopman]

I have experimentally extended the PC92 A record so that it adds the IP 
address to the callsign and I am now logging these to the standard log

An example:

PC92^GB7DJK^46801^A^^5GB7BAA:193.82.116.50^H99^

another (longer) example:

PC92^GB7DJK^46769^A^^1W3ZJ:216.36.25.224^1W8WY:68.73.99.169^1AB5C:69.149.51.91^1HB9HFN:217.162.35.235^1K5FNQ:98.183.93.41^1ZL4DH:124.198.140.52^1KU1T:71.176.128.160^1W5JAY:70.178.209.64^1KA1ALN:76.19.184.207^1AC4M:67.44.220.164^1W4WIV:67.235.39.199^1RU3UA:83.143.153.27^1KD8GOX:75.134.127.244^1KF4IBU:70.145.165.178^1N4LV:208.17.73.135^1G5LP:90.217.45.103^1K3IE:68.209.200.84^1OZ1CCM:80.160.57.62^1W1GY:67.189.253.200^1ON7KO:81.82.2.166^1SM5CBN:81.228.138.240^1IW2NXI:79.11.20.119^1KA9MOM:76.217.93.9^1OZ1DSD:217.198.212.252^1K8EM:151.213.214.6^1N2MAD:69.117.39.153^1IZ2NZM:79.44.80.44^1LA2ERA:85.166.91.71^1K0ABC:75.28.54.69^1YO4BTB:86.122.53.220^1PA3GXJ:94.209.63.221^1DL1DTC:141.51.157.23^1W4HTD:68.18.93.168^1DJ5OW:84.179.82.111^1DJ6LB:85.181.181.117^H99^

There are some things to note:

* in theory a callsign field is now:

   digit callsign : version : build : ip address

   but A records never have version or build so I cheat and leave
   out the spare : characters. But please be able to cope with the
   full version of the field as well (just in case).

* an IP address is either a normal dotted quad or a mangled IPV6
   address. Sadly I choose the wrong character for PC9x additional
   information separator so an IPV6 address will have its : characters
   replaced by ',' in the PC92 "on air" format so Brendan's IPV6 call
   would be:

   PC92^GB7DJK^12345^A^^5EI7MRE:2a01,348,6,26b,2^H99

   and the address needs a s/,/:/g to convert it back again for internal
   use.

   Note the possibility of hex characters!

This is currently working on a branch of the DXSpider code on GB7DJK and 
I shall be rolling out to GB7BAA and WR3D soon.
