I'm a technologist celebrating 15 years on the Internet. I've worked with organizations large and small and across multiple verticals to include financial, life sciences, consulting, retail, marketing/media, gaming, and the public sector (federal and state).

My experience spans from layer 1 (designing and installing physical infrastructure) to layer 7 (app development) and layer 8 (managing programs and projects).

I enjoy a good conversation, technical or otherwise. Feel free to reach out to me if you have any questions or comments.

comment Does my small network need a domain name?
Specific to the BIND comment, since it sounds like you're a Windows shop, replace BIND with MS DNS server. It's a service available on most (all?) "Server" operations systems (with the exception of 2008 Web). Backtracking a bit, you may need to point internal clients to the internal DNS server and let the internal DNS forward to public DNS servers for external query resolution. You might be able to setup a .local domain on OpenDNS and set suffix search order on local clients to prefer local first, but that can expose your internal IP scheme to the public.

comment How to set up an alternate domain while duplicating CNAMEs
Well, if you defined $ORIGIN in your a.com zone file, then changing the value from a.com to b.com would, in essence, replicate the a.com zone to b.com without using CNAMES. Alternatively, you could use a simple regex (or wordpad) find/replace function to edit the zone files.

comment enable large DNS queries on Microsoft 2008 R2 DNS server
Can you elaborate more on what you're trying to accomplish? DNS usually connects over udp for small queries and uses tcp for larger queries.

comment Cannot resolve domain from within LAN
can you connect (to a service, i.e. www (assuming you're planning to host some sort of server)) to the dynamic IP (should be a public IP address) from within the local network? In general, you shouldn't have to setup a local dns server for external dns resolution with dyndns to work. You'd need to have your dns resolvers on clients point to a dns server (forwarder) of some sort (public ones are 4.2.2.1-4, and 8.8.8.8).

+1 - I'd also add that it makes sense to assume the credential is compromised if such a situation occurs.

comment NFS (with Kerberos) mount failing due to “Server not found in Kerberos database” error
Can you add the correct PTR records into DNS for SOL and MERCURY? in general, the SOL and MERCURY should be an A record with one IP address and the PTR record should also point back to SOL and MERCURY and see if that makes a difference?

comment How to test if DNS information has propagated?
joeqwerty's absolutely correct. dns servers will cache a positive or negative hit for a predefined time. However, in addition to the original post, there are several public name servers you can check against including the old GTE (4.2.2.1, 4.2.2.2, 4.2.2.3, and 4.2.2.4) and google (8.8.8.8, 8.8.4.4). Simple rule of thumb, new changes can take up to the duration of the ttl for positive or negative hit. However, there are instances where apps implement bad logic and cache answers for a longer period of time.

Actually, F5, Citrix/NetScaler both offer virtual appliances for GSLB. A10, radware, zeus, brocade, alteon, and others may very well offer virtual appliances as well. But you're absolutely right that there are GLSB SaaS service providers out there. Probably easier on the pocket book by using opex instead of capex to build infrastructure but SaaS models aren't without its risks (i.e. SLA, operational, support). I've never heard of edgedirector or dnshat, but they are both competitively priced!
