DD Form 2490-42 occupies a particular place in Defense recordkeeping. Its title is Network Planning and Configuration Data - Zone Restriction Worksheet, and it exists to Network Planning and Configuration Data - Zone Restriction Worksheet. What the DD prefix records is an administrative judgment made long before your copy was printed: this transaction was determined to be common to the whole Department rather than peculiar to one service, and so the documentation of it was standardized at Department level.
That decision has consequences you will notice. Because not stated prescribes the form for the Department as a whole, and not stated maintains it on the Department's behalf, the same blank passes between the Army, the Navy, the Air Force, the Marine Corps, the Space Force, the Coast Guard when operating under Defense jurisdiction, the defense agencies and the combatant commands without translation. A clerk in one component reads a record created in another and finds the fields where they expect them.
Current edition: not stated, status not stated. Understand why that date is worth attention here. When the Department reissues a form, the replacement takes effect across every component simultaneously, so an older copy is not merely locally out of date — it is out of date in every office that might receive it.
The form is laid out top to bottom in a sequence that reflects how the record will be read, not merely how it was drawn. Identification comes first because everything below it is understood in relation to a named person, unit or transaction; substantive entries follow; certification closes the document because certification attests to what precedes it. Filling out of order tends to produce internal inconsistencies — an entry that made sense before the header was settled and does not afterward.
Verify the printed edition against not stated first. Field structure shifts between editions, and the office that receives your record is reading the current one. That office may sit outside your service, which removes even the informal accommodation you might expect from a colleague who used the old version last month.
For an ambiguous field, read the form's own instruction, then not stated, which controls.
Download the form
The set published here is PDF, covering 1 pages with roughly unknown fields. More than one format survives because the Department serves users under very different conditions, from a desk with current software to a location where a printer is the only reliable output.
The difference between a fillable and a printable pdf is a difference in what the file contains. A fillable release carries an interactive layer: each box is a defined field with a name and a data type, and what you type is stored as data inside the document. A printable release has no such layer — it is an image of the page, and the only place your answers can go is onto paper. The distinction matters downstream, because a Department record often gets scanned and forwarded several times before it reaches its final file, and typed characters survive that chain in a way pen strokes do not.
Route the executed form as not stated or local guidance directs, and retain a duplicate first. Cross-component routing is ordinary for DD forms, which is precisely why a personal copy earns its keep: the receiving office may belong to an organization you have no standing to query about a missing document.
Forms referenced inside this one are located by number alone, and that simplicity is a direct product of Department-level numbering. Because the DD sequence is maintained centrally and not duplicated by service, a number is a complete address: one number, one document, throughout the Defense establishment.
Where a service form is cited in the same instruction, the two numbering systems should not be read across. DA numbering belongs to the Army and is administered by an Army proponent; DD numbering belongs to the Department and is administered by not stated or an equivalent Department office. The systems developed separately and were never harmonized, so identical digits in each identify two documents with nothing in common. The prefix, not the number, tells you which system you are in.
Understanding why editions change explains why checking them is not optional. Revision follows directive reissue, changes in what data is required, and amendments to mandatory notice text — decisions made at Department level and communicated through publication rather than notification. The file you saved does not update itself, so the edition date at download is what you rely on.
The role of this page is narrow and worth stating plainly. It makes a published Defense form available and explains its structure. It does not advise, does not interpret policy for your circumstances, and cannot indicate how any office will treat a completed copy — those judgments rest with the authorities that own the process. Direct such questions to not stated, to the administrative office that services you, or to the authority named in not stated.
