[c-nsp] OT - Infoblox vs. Bluecat

[Church, Charles]

I apologize for this being fairly OT for a Cisco list, but I figured someone on here has touched some DNS gear before.  Anyone work with Infoblox and Bluecat, and run across a significant reason to choose one over another?  I've googled, but most articles are 5 years or more old.  Off-line responses encouraged.  The planned use is for govt, so full access to the kernel is nice for hardening/verification.  Also need TSIG, DNSSEC, and IPv6 support, which they both claim to have, as they're both based on recent bind.  Secure mgmt such as SNMPv3, SSHv2, and SSL would be nice.

Thanks in advance,

Chuck
