This section contains a number of articles and opinion pieces concerned with DNS and other loosely related matters. It is a mixture of rants and observations, with the occasionally useful bit of information lurking like a pearl in an oyster bed.
| Topic | Notes |
| The Death of Hope | Why the top level domains, especially country domains, should be secured (signed) as a matter or priority. |
| Open DNS - Bad Idea | Why an Open DNS is a bad idea and how to close it |
| DNSBL Services | Description of DNS based Black List (and White list) services. |
| DLV = DNSSEC without the Wait? | DLV, available in BIND since 9.3.0, may offer an alternative to waiting for ICANN and all the gTLD, ccTLD and sTLD operators to sign their zones. |
| DNNSEC - A Commercial Opportunity? | Is there money in DNS security? Some thoughts on turning DNNSSEC (and/or DLV) into a commercial opportunity. |
| Minimum TTLs | It's an apparently simple question - what is the mimimum sensible TTL? And the answer - well it's not that simple! |
| Failover Strategies | Is a short TTL or are multiple RRs the best failover strategy when using DNS? For browser based applications multiple RRs win - no contest. |
| TTLs - Revisited | We recently had cause to reflect on TTL values after a major outage caused by an access problem. |
| The Case Against DNSSEC | This article (published in circleid.com) itemises four major points are used against DNSSEC by naysayers together with the contra arguments from the point of view of a, perhaps relucant, DNSSEC believer. |
