Change the address of a proxy

A mobile proxy is sold with a link that tells the modem to take a new address, and this is how the program walks that link for you. The path is Proxies in the left column, then Change IP on the row. There are four moments you would want it: by hand, before a launch, on a clock while a window is open, and around a whole pool at once.

Change it by hand

Change IP appears on rows that carry a link. The program measures the address now, walks the link, waits for the modem and measures again.

What you are told is the truth of those two measurements: changed from one address to another, still the same one, or answered but not yet checkable.

The link is walked directly

A change of address is a command to the seller, and sending it through the very channel that is restarting would return a broken connection instead of an answer. So the request goes straight out, not through the proxy.

Change before each launch

A profile can ask for a fresh address every time it opens, with the switch named Get a fresh IP before each launch in the profile window.

If the fresh address cannot be obtained, the profile is not opened at all and the reason is named. Opening it on the old address would be the quiet wrong answer.

Change on a clock

The profile window also offers to change the address while the profile is open: every ten minutes, every half hour or every hour.

Only open profiles are touched, and the first count runs from the moment the window opened rather than from the moment the program started.

Spread a pool around

Select the profiles on the Profiles tab and press Assign proxy in the bar above the list. Tick the option that spreads the library across them and each one gets the next entry in turn.

Profiles that are open right now are skipped and counted, and skipping one does not eat its place in the circle.

Where a change can fail

A seller that stays silent for twenty seconds, an answer that is not a success, or a link that tries to redirect somewhere else: all three are reported with the seller's own words.

A redirect off the original host is refused rather than followed, because one header would otherwise send the request anywhere.

What this does not do

  • It does not change an address without a seller link. Nothing in the product can order a new address on its own.
  • It does not promise that the address will differ. Sellers set their own limit on how often a modem may move, and an unchanged address is reported as unchanged.
  • It does not change the address of a closed profile on a clock. A closed window has nothing to protect, and every change costs money at the seller.

Where this is decided

Each claim above is one place in the code and one stand.

The seller link is walked, the outcome is reported honestly, and a redirect elsewhere is refused

Who is due for a change and who gets which address is decided by arithmetic that runs

A skipped profile does not eat its place in the circle

A link that would reach into a private network is refused when it came from outside

Questions

The seller answered but the address stayed the same.
That is said plainly rather than dressed up as success. It usually means the seller's own rate limit has not let the modem move yet.
Why was the new address not checked?
A modem needs a moment to come back up. When the check right after the change does not land, the known address is kept instead of being wiped.
How fast can the clock be set?
Ten minutes is the shortest period offered in the profile window, and a period written shorter than five minutes is raised to five before it is saved.
Does a change touch the profiles using that entry?
The address of the entry does not change, only the exit behind it. Profiles keep pointing at the same row.

Try it on one mobile proxy

The free plan gives two profiles, with no time limit and no card.
