Abstract

The Domain Name System defaults to using UDP for queries and replies with a DNS payload limit of 512 bytes. Larger replies cause an initial truncation indication leading to a subsequent handling via TCP with substantially higher overhead. An extension to DNS UDP requests is specified which frequently permits larger UDP responses thus reducing the need for use of TCP.
