Disclosed are methods and apparatus for efficiently and reliably handling DNS (domain name service) PTR (pointer) queries and replies across IPv4 and IPv6 networks. In general terms, an IPv4 DNS PTR query which is sent by an IPv4 device to an IPv6 DNS Server is intercepted or received, for example, by a network device configured with NAT-PT and DNS-ALG. The received IPv4 DNS PTR query is then translated into two different types of IPv6 DNS PTR queries: a query having an “IP6.INT” string and a query having an “IP6.ARPA” string. Both types of IPv6 queries are then sent to the IPv6 destination DNS Server. Whether the DNS sends an IP6.ARPA or an IP6.INT type reply or both types of replies back, a valid reply is identified (if present) and then translated before reaching the IPv4 device.

A method of operating wireless devices includes providing a plurality of sender nodes each having a respective message to wirelessly send to a receiver node. A probability distribution is assigned to a plurality of frequency channels such that a respective probability of selection is assigned to each frequency channel. At least two of the probabilities of selection are unequal. A respective frequency channel is probabilistically selected for each of the sender nodes according to the probability distribution. The messages are wirelessly sent from the sender nodes to the receiver node in the selected frequency channels. The receiver node is used to sample a first one of the frequency channels and a second one of the frequency channels. The second frequency channel has a higher respective probability of selection than the first frequency channel. If the receiver node sensed a signal in both the first frequency channel and the second frequency channel during the sampling, the receiver node is tuned to the first frequency channel and receives a remainder of the message on the first frequency channel.
