Guides

Design guides from our network practice, each short enough to read before the change window.

  • IPv4 Network Design

    Zoning, the DMZ, /24 standards, address containers and when not to use them.

  • IPv6 Design

    Why the /64 is fixed, /127 on links, nibble boundaries, SLAAC or DHCPv6, and PMTUD.
