That seems pretty vague. It would be better to say something like:


The aforementioned values for AdvPreferredLifetime and AdvValidLifetime are expected to be an appropriate default for most networks. In some networks, particularly where the operator has complete control of prefix allocation and where hosts on the network may spend long periods sleeping (e.g., sensors with limited battery), longer default values may be appropriate.
