I'm guessing it's related to IPv6 over Bluetooth Low Energy, which is currently working its way through the bowels of the IETF:

https://tools.ietf.org/html/draft-ietf-6lo-btle

Basically, they saw what a glorious success 6LoWPAN (IPv6 over 802.15.4) has been (</sarcasm>), realized BLE/L2CAP has a fair bit in common with 802.15.4 (focus on minimizing power consumption, low data rates, crazy small per-packet payload sizes), and decided to reuse 6LoWPAN's IPv6 header compression (RFC 6282) in this IPv6-over-BLE standard.

To be fair, 6lowpan has suffered in no small part due to 802.15.4 itself having no real deployment outside of use for proprietary mesh network protocols.

BTLE has far, far, far wider hardware deployment.

while 6LoWPAN hasn't seen as wide adoption as I would have expected it appears that much if the standard will be implemented by google's THREAD, although not guaranteed success I'd not dismiss 6LoWPAN just yet
