IP Addressing and Network Services

New Brunswick Community College · Moncton, Canada · Academic work, 2023–2025

March 2024 · Evidence scope stated below

1. Project overview

IPv4/IPv6 client addressing, DHCP options and VLSM planning.

2. Objective

Provide consistent addressing and distinguish assignment, gateway discovery and DNS provisioning.

3. Environment and technologies

Cisco IOS; IPv4 subnetting; VLSM; DHCPv4; DHCP relay; IPv6; SLAAC; stateful/stateless DHCPv6; DNS.

4. Architecture

Original Lab 4: client PC → switch → router supplying dual-stack addressing. Relay/multi-VLAN requirements are related coursework, not observed extensions of this exact lab.

5. Technical implementation

  1. Lab4-DHCPsubmit.docx specifies first-ten-address exclusions, gateway/DNS options and client ipconfig checks.
  2. IPv6 coursework assigns link-local/global addresses and enables routing for SLAAC; the report records FE80::1 as a gateway answer.
  3. Stateful DHCPv6 uses a pool, interface binding and managed flag. DNS and gateway behavior are checked separately.
  4. The pool image records rejected syntax followed by ipv6 nd prefix default no-autoconfig, then one active client. Relay/stateless completion remains unverified.

6. Configuration examples

Selected actual console transcription; final relay pattern is illustrative.

! Selected recovered console lines/output:
ipv6 nd prefix default no-autoconfig
show ipv6 dhcp pool
DHCPv6 pool: joshv6pool
DNS server: 2001:DB8:1AB:28::5
Domain name: lab5.v6
Active clients: 1
! Illustrative relay pattern, not recovered configuration:
ip helper-address <dhcp-server-address>

7. Security considerations

Exclude infrastructure addresses from dynamic pools and validate intended relay destinations. The image uses an academic IPv6 documentation prefix.

8. Troubleshooting

A corrected prefix command and one active client are bounded observations, not proof of all DNS and dual-stack paths.

9. Verified result

The original DHCPv6 pool photo shows one active client. A separate binding photo was inspected but its client identifier is not published. Full dual-stack acceptance remains unverified.

10. Original evidence

Original Lab4-DHCPsubmit.docx: worksheet, written answers and six embedded images. The pool image is shown below.
