What is DNS?

•  Associate names to addresses

•  Giant distributed database

•  2 Types of DNS Servers

•  Recursive – performs the lookup

•  AuthoritaAve – Replies with the answers

DNS = Domain Name System


A Basic DNS Lookup


•  All stored in a zone file

•  Many different types with different data

•  A Record: IPv4 address

•  AAA Record: IPv6 address

•  MX: Mail Server

•  CNAME: Alias to another DNS name

What is it we are asking for?

A DNS Record


It’s a bit more complicated…

I’m in the details!


It's a bit more complicated…

•  Caching at all levels

•  MulQple Data Centers & fastest route algorithms

•  Loading Balancing

•  Failovers

•  NX: No record found handling

•  PropagaQon Time

•  DNSSEC: Think hUps at the DNS level

•  Access control & zone ediQng

•  Dozens of record types (A, AAAA, MX, CNAME, etc.)

The devil is in the details


Managed DNS

•  Offloads data center upkeep

•  Allows for responses from mulQple points around the world

•  Handles the implementaQons of load balancing, failovers, geographically specific responses, etc.

Takes care of most of the details


Managed DNS

•  Gives you a simple zone editor and

user access control

•  Lets you focus on your specialty instead of DNS

•  Dyn’s Enterprise DNS offering is DynECT

Takes care of most of the details

•  Robust –  4 levels of

failover –  SLA

•  ElasQc •  Distributed

–  Edge Caching

–  Geo-‐rouQng


DynECT API

Asynchronous •  Start a job: reply is immediate

•  Call back to ask if job has finished

•  Unblocks user during long operaQons

•  Libraries allow for synchronous access by hiding the blocking

RESTful API


DynECT API

•  JSON

•  XML

•  YAML

•  HTML/Querystring (limited)

Supported Data Forms


DynECT API

•  All zones and nodes & all record types

•  Advanced services

•  Users

•  Permissions

What can be accessed?


DynECT API

•  YES!

•  We provide a WSDL

SOAP?


DynECT API

•  Full documentaQon online

•  SecQons specific to REST and SOAP

•  Most examples we provide are REST (C# is SOAP)

•  There examples in many languages

DocumentaAon & Examples

•  Python •  Ruby

•  Perl •  C#

•  Java •  PHP


Tell me more!

Shameless Plug Alert!!!

Check out the blog I wrote for ge\ng started with the API: hUp://bit.ly/10dqCtz


Tell me more!

Find some great examples on Github

Dyninc Dyninc-‐cs


Tell me more!

•  Bulk changes to mulQple zones or records

•  Keeping advanced services in sync with local DNS

•  CreaQng single point tools to update mulQple DNS providers

What would I use your API for?


Thank You!
