I am a web developer, ColdFusion programmer, dba, software architect, and systems and network administrator through my consulting business, Ziggy Consulting.

I used to own and operate DtDNS, a DNS hosting and management service with a focus on dynamic DNS services. I started DtDNS in March 1999 and sold it to another company in February 2011.

I also love to fly since I earned my private pilot certificate in 2008.

My primary work is web development with ColdFusion, but I also manage networks of remote thin clients deployed as kiosks, a number of web servers at various locations, and a small data center for a web development/hosting company.

comment Nameservers: Can I setup 5 ips to 1 server and have only 2 nameservers?
Your e-mail and DNS can be on entirely different systems and often use different domain names. For example, if I own example.com and have mail.foo.com as my mail provider, I would just add an MX record to the example.com zone and point it to the provider as @ IN MX 10 mail.foo.com. The mail server will then need a reverse DNS entry which corresponds to its IP address, and preferably one that has a host which also resolves back to the IP. That reverse name doesn't have to have anything to do with the domains actually hosted on that mail server and the DNS host can also be different.

comment How to Monitor Bandwidth usage in real terms
That office environment was not your typical locked-down corporate prison; they were all pretty technical people (developers) who all brought in their own systems to work on (laptops), so they weren't using a domain with software installation restrictions or anything of that sort. Everyone was essentially their own administrator for their own box.

comment Keyboards for kiosk/outdoor/abusive environments?
Thanks John, we may have to do something like that. We looked at the types of things used by places like McDonalds that can take a lot of continual use but they rely on thin plastic overlays which can be easily torn off, cut, ripped, etc. and wouldn't last long out in public. We may just have to go the ultra-rugged route or try to roll our own at some point.

comment Moved DNS and Email Hosting, Now Can't Send/Receive To/From Domains Hosted on Previous Host
From the information provided, it does in fact appear that the old provider still has outdated DNS information on their name server which they will need to remove. If they don't have a clue as to how to do this, I'd move everything away from them sooner than later and use a provider with employees that know what they're doing.

comment Moved DNS and Email Hosting, Now Can't Send/Receive To/From Domains Hosted on Previous Host
It could be an old zone file, but I was referring to the mail server configuration itself (i.e. the mail server could still be set up to handle mail for the domains that are no longer pointed to it).

comment Is it possible to get all the domain names assigned to an IP address?
It's not a "direct" solution, but there are companies out there that aggregate network information. ServerSniff.net has a tool that will list all of the domains they know of that direct to a given IP address. It's not 100% accurate or fail-safe, but it's a good place to start. serversniff.net/content.php?do=hostonip

comment Bind and Open Ports
I'd also note that TCP 53 may need to be opened even if you don't have an external secondary requesting zone transfers. If a DNS request is too large to fit into a UDP packet, it will be sent via TCP. Likewise, if a received response is too large, it will be truncated and the requester will resubmit the request via TCP to get the full response. This will happen more as DNSSEC becomes more widespread.

comment How do I setup my DNS so the FQDN server serves its own DNS?
I'll also mention that DNS uses both UDP and TCP on port 53, so ensure that it's open for both protocols.
