EngineerSquadHQ — Practical Tooling for Network and Systems Engineers
EngineerSquadHQ is a bilingual engineering workbench built for the people who design, deploy and defend
networks every day. The platform brings together the calculators, planners, reference libraries and audit
utilities that network engineers, systems administrators and security teams normally keep scattered across
spreadsheets, bookmarks and half-remembered command notes. Everything runs in the browser, works in English
and Arabic with full right-to-left support, and adapts to light or dark environments so it stays readable in
a bright office or a dim network operations centre.
Addressing, Subnetting and IP Address Management
Plan address space with confidence using IPv4 and IPv6 calculators, VLSM breakdowns, CIDR summarisation,
subnet overlap detection and a full IPAM workspace. Convert between decimal, binary and hexadecimal
notation, normalise MAC address formats, and generate consistent VLAN and DHCP scope plans for campus,
branch and data centre designs. Every result is copy-ready so it can drop straight into a change record or
a device configuration.
Design, Capacity and Migration Planning
The network design generator turns organisation details and a chosen security posture into a topology
diagram, VLAN and subnet plan, bill of materials, phased implementation schedule, test checklist and a risk
register. Capacity tooling covers bandwidth, power over Ethernet budgets, fibre optical power, wireless
capacity, rack and power layout, MTU and MSS sizing, high availability options and cloud quality of service
planning. Migration and documentation generators keep the paperwork aligned with the build.
Security, Vulnerability Research and Auditing
Search live CVE data by vendor, product and version, review CVSS severity, exploited-in-the-wild flags
and recommended upgrade paths, then confirm the fix with configuration comparison and configuration audit
tools. The SysAdmin suite adds DNS records, WHOIS, IP and ASN intelligence, TLS certificate inspection,
HTTP header review, redirect tracing, port reachability checks, encoders, validators and hash generators.
The premium site audit grades SEO, security headers, performance, accessibility, mobile readiness,
technical hygiene and content depth, then lists prioritised, bilingual recommendations.
Learning and Team Enablement
Structured guides explain the OSI model, TCP/IP behaviour, subnetting arithmetic, VLAN and trunking
design, routing protocols including OSPF and BGP, DNS and DHCP operation, wireless fundamentals, firewall
policy design and cloud networking patterns. Junior engineers can follow the guides while senior engineers
use the same tools for production work, which keeps terminology and documentation consistent across a team.
Access and Plans
Core calculators, converters and reference libraries are free to use. Advanced planners, analysers and
premium audits are available on a monthly or annual subscription. Enable JavaScript to load the full
interactive application, or contact the team at Leader@engineersquadhq.com with questions about access,
billing or feature requests.
