Does the "(since glibc 2.3.4)" apply to the option, or to the "then nibble format is used"? It's not clear. If the former, then write .BR RES_USEBSTRING " (since glibc 2.3.4)" If the latter, then write "then (since glibc 2.3.4) nibble format is used". > +.TP > +.B RES_NOIP6DOTINT > +Use > +.I ip6.arpa > +zone in IPv6 reverse lookup instead of > +.I ip6.int s/.I ip6.int./IR ip6.int ,/ > +which is deprecated since glibc 2.3.4.
