* Fixed the default values of HorizPre and VertPre According to RFC-1876 those fields should be: "a pair of four-bit unsigned integers, each ranging from zero to nine, with the most significant four bits representing the base and the second number representing the power of ten by which to multiply the base. This allows sizes from 0e0 (<1cm) to 9e9 (90,000km) to be expressed" Current values for HorizPre and VertPre (165=0xA5 and 162=0xA2) are incorrect because the first HEX digit is greater then 9 The default values should be: HorizPre = 10000m = 10000 * 100 cm = 10^6 = 0x16 VertPre = 10m = 10 * 100 cm = 10^3 = 0x13 Size = 1m = 1 * 100 cm = 10^2 = 0x12 The value of Size was correct, but this PR changes it to HEX representation to be more readable * Informative comments Made comments on LOC record default field values more informative Co-Authored-By: Richard Gibson <richard.gibson@gmail.com> Co-authored-by: Richard Gibson <richard.gibson@gmail.com> |

README.md
Alternative (more granular) approach to a DNS library
Less is more.
Complete and usable DNS library. All Resource Records are supported, including the DNSSEC types. It follows a lean and mean philosophy. If there is stuff you should know as a DNS programmer there isn't a convenience function for it. Server side and client side programming is supported, i.e. you can build servers and resolvers with it.
We try to keep the "master" branch as sane as possible and at the bleeding edge of standards, avoiding breaking changes wherever reasonable. We support the last two versions of Go.
Goals
- KISS;
- Fast;
- Small API. If it's easy to code in Go, don't make a function for it.

Building
This library uses Go modules and uses semantic versioning. Building is done with the go
tool, so
the following should work:
go get github.com/miekg/dns
go build github.com/miekg/dns
Examples
A short "how to use the API" is at the beginning of doc.go (this also will show when you call godoc github.com/miekg/dns
).
Example programs can be found in the github.com/miekg/exdns
repository.
