Expand description

Determines which error was run into during parsing.

For ones that contain lengths, this tells which length was encountered during parsing. For example, RDataLen is a pretty general error relating to the RData being the wrong size for the included type (both the size and type are included. More below).

For RData errors: – Type::A the size was not found to be an IPv4 address. – Type::Aaaa the size was not found to be an IPv6 address. – Type::Srv the size of RData was not large enough to fit a SRV record header as well as a payload.

BadPointerIndex returns the last encountered pointer that attempted to reference data beyond the bounds of the available packet buffer.

LabelTooLong refers to there being too long of a label byte when parsing.

DomainTooLong refers to overrunning the maximum size of a domain (255 bytes) when parsing.
