That's nearly impossible here, those people seem to be paid to bounce
questions! I know, I worked for them, on another branch.
And anyway, it doesn't matter that much to me.

There is a command on the router (it runs linux 2.4.17) that tells the
IP:
[warning: long lines]
] -> wan show
] VCC Con. Catego. Service Interface Proto. IGMP Nat
QoS State Status DialMod IP
] ID Name Name
address
] 0.8.32 1 UBR pppoe_8_32 ppp_8_32_1 PPPoE Disable
Enable Enable Enable Up Direct 88.*.*.*
] 0.8.36 1 UBRwPCR pppoe_8_36_1 ppp_8_36_1 PPPoE Disable
Enable Enable Enable PPP Down Direct
If I wanted, I would just have to write a script sshing to the router and
issuing the "wan show" command. Perhaps there is another way after I read
the manual someday.
For example, I might get some info with snmp, if I learn how it works:
[EMAIL PROTECTED]:~> snmpget -v 1 -c public router system.sysDescr.0
SNMPv2-MIB::sysDescr.0 = STRING: Broadcom Bcm963xx Software Version 2.20L.01
But I have no idea what command strings it has, nor how to learn them :-(
[...]
Perhaps this:
snmpwalk -v 2c -c public router
it gives 251 parameters, but none seems the IP. Pity.

Another way is to send myself an email and parse the headers.
And, this router has also support for dyndns or something similar. But, as
I said, I don't need it (yet), it is just a curiosity.

True. One day I'm bored enough ;-)
