1. watchA

委譲先が別ペア(active)を返すのをよく見かけるので、真似てみた。

2. 手順

  1. active 化 (kurt+deborah) zone あり。
  2. 別ペアに委譲しなおし。 (sri+lia, sriにzone は作っていない)。
    • lia にゾーンあり。activeでも自分のもつゾーンを返答する。
  3. sri, lia の返答を確認する。(deborah, kurt も)

3. whois

4. active

kurt+deborah で active に (さくらでの操作) -- ToshinoriMaeno 2021-02-07 21:42:46
