Department of Defense form 2490-31. Official designation: DD 2490-31, Network Planning and Configuration Data - NNXX Routing Worksheet. This form has not been set up to work with a text-to-speech reader. Contact the DoD Forms Manager for further details if this access is required.. Purpose: Network Planning and Configuration Data - NNXX Routing Worksheet. Current edition not stated, status not stated.
Governing directive: not stated. Responsible office: not stated. The DD designation signals joint scope — all military departments, combatant commands and defense agencies draw on a single edition of the document.
Common users: service members regardless of branch, Defense civilian staff, and the offices that file, verify or retain the finished document.
Timing of submission is fixed by not stated and by the implementing guidance of the submitting organization. What follows describes the blank document, not agency procedure.
Formats offered: PDF. Length: 1 pages. Fillable field count: roughly 200.
Pdf serves as the base format. In the fillable variant, each box is an interactive field that holds typed text inside the document. In the flat printable variant, no fields exist — the page prints as a blank to be completed by hand. Typed entries survive transmission; handwriting does not always survive scanning.
Xfdl is present in the set. The format belongs to IBM Lotus Forms — long the Defense standard for electronic forms — and needs the matching viewer; pdf applications will report the file as unreadable.
Every listed format is free to download. Modern pdf software handles the pdf files, with the caveat that browser-embedded viewers sometimes ignore field properties that a desktop reader honours.
What the form asks for
- Press this Reset button to clear the data from all fields.
Order of completion: identification block first, substantive entries second, certification and signature last. The blank is laid out in that sequence and the sequence is not arbitrary — later entries often depend on data established in the header.
The current edition is not stated. Superseded editions of DD forms are frequently rejected at the receiving office, since Department-wide forms change centrally and older layouts lose their field correspondence. Edition date appears in the lower corner of the printed blank.
The signature block takes an actual signature. On paper this means ink; electronically it means a credentialed digital signature, commonly CAC-based. Typed text in a signature field satisfies neither.
Where personal information is collected, a Privacy Act Statement appears on or with the form. It names the collection authority, the purpose, the routine uses of the data and the consequence of withholding it. Reading it precedes filling the form.
Errors seen most often involve edition mismatch, empty mandatory fields, illegibility after scanning, date formats inconsistent with the printed instruction, and unsigned or undated certification.
Guidance for specific entries sits on the form face and in not stated; the directive is authoritative where the two do not agree.
After completion, the copy goes to the office designated by not stated or by local procedure. Retention of a personal copy is ordinary practice and costs nothing.
Cross-referenced forms are found through the numbering system. The DD sequence is Department-level and unified, which means a number cited on the page identifies one document across the whole Department.
Where a DA form is cited alongside a DD form, the two belong to different systems: DA numbering is Army-specific and administered by an Army proponent, while DD numbering is Defense-wide under not stated or an equivalent Department office. Numbers do not translate between the systems.
Forms are reissued for several reasons: directive revision, changed data requirements, updated notice language. Confirming not stated at the moment of download covers the risk.
The material here is descriptive. Nothing on the page constitutes legal or procedural advice, and no statement here determines whether a submitted form will be accepted. Such questions go to not stated, a servicing administrative office, or the authority identified in not stated.
