PTR registration question (Class B vs Class C blocks)

Hi guys,
What is the best practice when it comes to registering the PTR records for a whole Class B network? If lets say I've got the whole range 10.10.0.0/16 to register, should I split it up into individual Class C blocks (ie: 10.10.1.0/24, 10.10.2.0/24, 10.10.3.0/24, etc) or is it recommended to just leave it as a Class B entry?

For my config file, which one is the normal best practice? How should my zone/data files look like too?

Entry 1 :

zone "10.10.in-addr-arpa" {
  type master;
  file db.10.10;
}


OR


Entry 2 :

zone "1.10.10.in-addr-arpa" {
  type master;
  file db.10.10.1;
}

zone "2.10.10.in-addr-arpa" {
  type master;
  file db.10.10.2;
}

zone "3.10.10.in-addr-arpa" {
  type master;
  file db.10.10.3;
}

zone "4.10.10.in-addr-arpa" {
  type master;
  file db.10.10.4;
}

zone "5.10.10.in-addr-arpa" {
  type master;
  file db.10.10.5;
}

Thanks!
