Re: [6lo] I-D Action: draft-ietf-6lo-dect-ule-04.txt

Sorry for the double post, but I'm adding my comments on 3.2.1 to this
thread
where they belong.

Delete the sentence that reads

Least significant bit of this address is the last bit
in network order.

In the sentence that reads

First bit is set to a one for addresses derived from
the RFPI and first bit is set to zero for addresses
derived from the IPEI.

You either want to substitute "i/g bit" or "8th bit" for "first" (two
places)

In the sentence that reads

>From these intermediate 48 bit addresses are derived
IIDs accordig to the guidance of [RFC4291].

s/accordig/according/

In the sentence that reads

In the derived IIDs the 7th bit is set to one to indicate
that the addresses are not global unique.

s/one/zero/  (See RFC 4941, Appendix A; note the u/l bit gets inverted in
the IID)
s/global/globally/

In the sentence that reads

For example from RFPI=11.22.33.44.55 the derived IID is
82:11:22:FF:FE:33:44:55 and from IPEI=01.23.45.67.89 the
derived IID is 02:01:23:FF:FE:45:67:89.

s/82/01/ and s/02/00/  (this is the net effect of the corrections made
above).
