Yes, it means that NSF supports IKEv2. Thanks for the comment. We will rephrase this sentence

We have defined a range. This range also appears in RFC 4301 as:

IPv4Range ::= SEQUENCE {    -- close, but not quite right ...
           ipv4Start   OCTET STRING (SIZE (4)),
           ipv4End     OCTET STRING (SIZE (4)) }

And here

"SPD entries were redefined to provide more flexibility.  Each SPD
     entry now consists of 1 to N sets of selectors, where each selector
     set contains one protocol and a "list of ranges" can now be
     specified for the Local IP address, Remote IP address…”

Hope this helps.

Best Regards.
