Dsl_trib_59nu Provides 2 Ip Address's ?


as obvious from the title ... i have TriBand DSL NU Plan, changed from earlier (crappier) DSL_399
ive noticed a change in the Account Summary section of my User CP on the mtnl usage site.

Free ADSL MB balance for current month

IP Address 2

SO do i have 2 ip address's ? How do i know about 'em ?
What is this sposed to mean ? also if i check my IP thru a site it shows up as a dynamic ip.

Someone make sens eof this please . Yea, when i had earlier plan it showed 1 IP Add.
