 * The NSAP-PTR RR

   The NSAP-PTR RR is defined with mnemonic NSAP-PTR and a type code 23
   (decimal).

   Its function is analogous to the PTR record used for IP addresses [4,7].

   NSAP-PTR has the following format:

   <NSAP-suffix> <ttl> <class> NSAP-PTR <owner>

   All fields are required.

   <NSAP-suffix> enumerates the actual octet values assigned by the
   assigning authority for the LOCAL network.  Its format in master
   files is a <character-string> syntactically identical to that used in
   TXT and HINFO.

   The format of NSAP-PTR is class insensitive.  NSAP-PTR RR causes no
   additional section processing.

   For example:

   In net ff08000574.nsap-in-addr.arpa:

   444433332222111199990123000000ff    NSAP-PTR   foo.bar.com.

   Or in net 11110031f67293.nsap-in-addr.arpa:

   67894444333322220000  NSAP-PTR        host.school.de.

   The RR data is the ASCII representation of the digits.  It is encoded
   as a <character-string>.

I'm Alphons van der Heijden, living in Lelystad, Netherlands, Europa, Earth. And currently I'm retiring from hard working ( ;- ), owning my own company. Because I'm full of energy, and a little to young to relax ...., I don't sit down, but create and recreate software solutions, that I like. Reinventing the wheel is my second nature. My interest is in the area of Internet technologies, .NET etc. I was there in 1992 when Mosaic came out, and from that point, my life changed dramatically, and so did the world, in fact. (Y)
