Split horizon Servers with the split-horizon DNS feature can give different answers depending on the source IP address of the query.
A number of workarounds were developed to locally disable the effects of Site Finder on a per-network basis. Most notably, the Internet Systems Consortium announced that it had produced a version of the BIND DNS software that could be configured by Internet service providers to filter out wildcard DNS from certain domains; this software was deployed by a number of ISPs.
Record types other than PTR records may also appear in the reverse DNS tree. For example, encryption keys may be placed there for IPsec, SSH and IKE.
